That’s a very good point of course - brain drain is a problem and we shouldn’t encourage it. I suppose I’d rather propose encouraging countries to offer refugees good educations. I am explicitly talking about jobs that require training and come with an expectation of a good life - I agree that the jobs in agriculture and slaughterhouses and such are inhumane.
I don’t think we should tell people not to have children. I just think that we should stop telling them that putting more humans on this world is the moral option or their duty. I think we should at least encourage people thinking of having kids to consider the consequences that has, and then leave the choice to them.
