> As a counterpoint, we in America certainly do not seem to be immune to sticking with flawed social constructs that impede our progress/happiness.

There are definitely counterexamples within the US, but in my opinion they are much milder, and often in pockets. Generally speaking, if I take and practice advice in a self-help book that goes counter to the American norm, I don't get social rejection, and I often get more encouragement than negative vibes.

Oh, and sports-worship is everywhere - wealthy and poor :-)
