Culture War Roundup for the week of September 11, 2023

This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.

Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.

We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:

  • Shaming.

  • Attempting to 'build consensus' or enforce ideological conformity.

  • Making sweeping generalizations to vilify a group you dislike.

  • Recruiting for a cause.

  • Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.

In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:

  • Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.

  • Be as precise and charitable as you can. Don't paraphrase unflatteringly.

  • Don't imply that someone said something they did not say, even if you think it follows from what they said.

  • Write like everyone is reading and you want them to be included in the discussion.

On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

Pointwise vs Uniform "badness"

Note: This post assumes the axiom that some people are better than others, and that we can to some degree of accuracy say whether someone is a net contributor to the world or not.

Often when it is pointed out that people who are in group X are a net negative to society (e.g. low paid cleaners who consume a lot more in benefits and general wear and tear on public goods like roads than they put in) others are quick to point out that actually these people are the lifeblood of the country and if they suddenly disappeared the country would collapse within a week (e.g. truck drivers refuse to work, thereby causing collapse as food doesn't get to where it needs to be etc.). This is then followed by the conclusion that therefore these people are not bad for society but rather good for it, and so we shouldn't complain about them at all.

I am completely convinced that they are correct that the country would indeed collapse in short order if truck drivers went on strike, cleaners stopped working etc. However this fact is a statement about the group as a whole, instead of individual members of it. For example: If a factory needs 5 people to work the machines but union regulations require them to hire 25 people instead of 5 then yes, each and every single member of the group of "workers" is a parasite sucking on the teat of the group of people who are "factory owners", even though the "factory owners" need the group "workers". In this case it is not the individuals who are indispensable to society, but rather the group as a whole, and the example above shows, it's possible for the group to be a net positive while every single individual in it is a net negative.

Of course not all groups of people are like this. The group of people who are criminals is a net negative to society full stop (restrict criminals to those who commit non-state sanctioned violence+thieves if your worried about how exactly criminal is defined). The individual members of this group are a net negative to society and the whole group is a net negative too. This is probably why "criminals bad" is a much less controversial statement compared to "street cleaners bad" even though someone who earns enough to be a net contributor plus does some light burglary on the side is probably much less of a drain on public welfare.

To be clear here: the people who are members of a net positive category but themselves are net negative are still those who society would be better off without on the margins. And since all economic decisions are made on the margin it is perfectly valid to say that ceteris paribus the world as a whole would be better off without them in expectation.

I think it makes sense to distinguish these two types of a group being bad for society. Firstly we have pointwise badness as an individual which we define as a person who is on their own a net negative to society ceteris paribus holding everything else the same (i.e. we remove them and just them from society and ask if the result if better or worse in expectation). From this we can define pointwise badness for groups where a group is given this label if most of its members are pointwise bad as individuals (note: here we depart from the mathematical definition, every group has it's saints, I'm sure there are some net positive criminals so we don't require every single member of the group to be a net negative).

As examples the group of Criminals are pointwise bad for society, equally street cleaners are pointwise bad for society because they are easily replaceable and consume more than they output.

Then you have uniform badness, which is when the group as a whole is a negative influence on the world and if we could somehow Thanos snap every single member of it away the rest of society would be better off. Criminals are uniformly bad for the world, while street cleaners, truck drivers and steel mill workers are not. Note that uniform badness sort of implies pointwise badness in the real world (not exactly: a group with 10 good people but 1 Literally Hitler is uniformly bad for the world, while it wouldn't be pointwise bad, the Literally Hitler is pointwise bad as an individual, but none of the others are) much more than pointwise badness implies uniform badness.

There are lots of pointwise bad groups but much much fewer uniformly bad groups. Generally when people are talking about how members of a group are bad, especially when they want something to be done they're talking about pointwise badness rather than uniform badness.

@sodiummuffin and greyenlightenment's points below are correct: underpaid "essential workers" only have low wages because there are so many people able and willing to do their jobs at low wages, relative to the "need" for those jobs.

Several years ago I saw a cleaners strike happen at a university. (The cause was dissatisfaction with a middleman temp firm which was taking a large cut of the budget allocated for cleaners' salaries). The hallways and lecture halls were messy after only 2~3 days, and after two weeks they were full of trash. At which point graduate students were paid extra to clean up the hallways and lecture pits. To have graduate students cleaning the hallways was much more expensive than having the cleaners do it, but the labor market was suddenly artificially tight, and the department feared that having trashy lecture halls would result in undergrad enrollment dropping.

In labor markets flush with workers, salaries are completely unrelated to the infrastructure that makes it possible for jobs to be done, as well as completely unrelated to the upper limit of what people would pay for that job to be done (i.e. what would be paid if there were absolutely no workers), despite the net value of their jobs to other people in society being several orders of magnitude larger than the prevailing salary. They cannot negotiate higher salaries because if they do then someone else will come in and replace them, getting the job by undercutting their wage.

The same is true in reverse: if there were only one person able and willing to do plumbing in the entire country, that person would be paid millions of dollars per hour servicing nuclear reactors. If there were only one person able to clean in the entire country, they would be paid handsomely to work in a semiconductor fab.

It's called paradox of value, or water-diamond paradox (water is a lot more useful than diamonds, but the price of diamonds is higher).

https://en.wikipedia.org/wiki/Paradox_of_value

I don’t think it’s a paradox of value. Realistically everything in every market has a consumer surplus. But prices settle where the marginal costs equals the marginal value.

If t-shirts were $10k I’d probably own one shirt and take really good care of it but since I can buy shirts for $20 I end up buying shirts until the very last one meets my utility.

Paradox of value though is an extreme example of a supply and demand curve. The diamond/water example is just the extreme where one product has very tight supply and one has very abundant supply. Cleaning services is really just more of a normal supply/demand curve where supply is available and adjustable. While the diamond supply has been relatively fixed in the short/long term (until recently since lab diamonds are taking over the market).

The paradox of value is that things that are more useful than others as a whole, like water, have a lower price than other scarcer things like diamonds.

Replace water with cleaning ladies and diamonds with software engineers and you get exactly the same situation as above

My point was both of these are just cases of normal supply and demand curves intersecting. Which also occur in every single market of which a cleaning lady isn’t in any way special compared to every other market. Nobody says the market for jeans is special and cleaning lady’s are similar to that market.

We don’t go around calling every market a paradox of value but ya clothes are valuable or I’d freeze. Oxygen is interesting because it causes death quickly when you don’t have it but the supply curve for the earth is unlimited quanitity at zero costs on earth.

Paradox of value is not a market, it's a phenomenon that can appear in any market: some things have a higher price than others that seem more necessary. It's something that must be explaned by the theory, and every economical theory (eg theory of labour value) has tried to explain it.

Supply and demand cruve intersecting is just a possible explanation of this phenomenon in marginal utility theory. Perhaps someone one day will come with a better theory and a better explanation, but as long as it is an economical theory it will have to provide an explanation for the paradox of value.

Seems like you are debating the entirety of Econ theory the stuff everyone agrees with that’s taught in intro to micro.

No I'm just explaining you the difference between the facts (the explicanda of the theory), like the price of diamonds and water, and the explanation of those facts (the theory itself), like supply and demand. It is true, however, that the theory is always more precarious than the facts
