It can't be true that both universal higher education and immigration are social goods, since it is cheaper to just not educate some percentage your own people.
This comment perplexed me until I realized you were assuming that the average education level of immigrants is lower than that of "natives" (that is, the pre-existing population of the country). But that need not be the case. To borrow from personal experience — many immigrants from the former Soviet Union are quite a bit more educated than the national average in the U.S. Surely immigrants who bring an above-average education with them are good for the society (assuming that they intend to become productive members of society)? Doesn't it follow that both of the things you mention can, in fact, be true, conditional on certain contingent properties of immigration?*
*And of higher education, presumably. I mean, we could say "higher education can't be a social good if we do it wrong in ways X, Y, Z", to which the obvious response is "we shouldn't do it like that, then."
What do you believe that most people on this site don't?
I'm especially looking for things that you wouldn't even mention if someone wasn't explicitly asking for them. Stuff you're not even comfortable writing under your own name. Making a one-shot account here is very easy, go ahead and do that if you don't want to tarnish your image.
I think a big problem with a "community" dedicated to being less wrong is that it will make people more concerned about APPEARING less wrong. The biggest part of my intellectual journey so far has been the acquisition of new and startling knowledge, and that knowledge doesn't seem likely to turn up here in the conditions that currently exist.
So please, tell me the crazy things you're otherwise afraid to say. I want to know them, because they might be true.
