It could be that as I've aged my perspective has changed, but our rugged individualism seems to be ranging ever deeper into sociopathy over the years. But then again you think about how the country was established through murder, bad faith, and theft (this shouldn't be controversial to anyone familiar with our forebears' tactics against the natives), then slavery, then indentured servitude, then robber barons, and I think maybe we've just never been very nice to one another. What humanitarian features have been added to government (abolition of child labor, Medicare/Medicaid, Social Security, etc) seem to be rooted in an America that came and went, when the working class was united against exploitation, rather than being demonized against one another based on cultural issues that have little to no impact on our day to day.
I've probably already crossed the line on the forum's rules so I'll shut up now.
