those terrible Walmart people !!
I believe this phenomenon is an unintended byproduct of the 60's "be yourself," "let it all hang out," paradigm. Before the cultural revolution of the late 60's/early 70's, Americans had the same levels of pride and shame as Europeans. Then something went terribly, terribly wrong.
I guess it is also Walmart's secret weapon for advertising! People will flock to Walmart, just to see all the weird and shocking sites!
