One of the major criticisms that many cite against increased spending on "social safety nets" in America is that individuals in other countries are much worse off than even the poorest in America. While I have always been very supportive of policies that increase social mobility and economic opportunity, I have often found troubling countering this argument. While one could invoke such principles as equality or special compassion for fellow Americans, I can't seem to invoke another argument for why we should care so much about the plight of poor Americans. Does such an argument exist? Or are we forced to rely on those aforementioned principles, which not everyone may accept?
