"you're not going win any medals (or fights) while holding by your usual ethical standards." That's the thing! These are not ethical standards. These are about the general rules by which a society operates. Generally countries with inclusive systems work better than countries with exclusive ones. China being the odd man out, apparently, at the moment. So it's not about ethics, it's about economics. It may seem like a value call, but actually it's a decision along a path does the society want to be more or less like an exclusive system. Since exclusive systems don't work as well financially, it's effectively a call does the system want to be wealthier or poorer long term.
