What do you mean “what is a labor market?” That we’ve had an open labor market is fairly modern, and even more modern is the idea of broad workers rights. Would you rather work in a factory now, or 150 years ago? Not everything is always getting better and there are ups and downs, but over a long enough time frame we’re clearly always trending towards better.

I guess I thought it was clear that I understand that soldiers still rape and pillage. But it being illegal anywhere is a fairly modern development.
