Shouldn't the US be ashamed of its overworked population and lands?

Because even American Catholics or non-Christians have drunk deep from the well of the Protestant Work Ethic. Plus modern culture socially rewards material success.

Can't decide if it's good or bad overall but I do think that's a strong part of it. Working v(and work's material fruits) are prized over other things.

It's easy to sneer at that (from my perspective anyway) but civilisation does need people like this. So it's a blessing and a curse
