One of the corrosive aspects of American popular culture has been the relentless corporatization of everything. I don't mean to complain when, say, private business is brought in to improve a benighted area as was famously done in Times Square. But all things fun - sports, big time stadium rock concerts, NASCAR, even skateboarding(!) - have been turned into mega-events only affordable to corporate interests, especially financial ones(that at least will change!). In a symbolic sense, true fans are locked out in favor of their bosses and bankers. Think of Montgomery Burns trying to mix with ordinary joes by saying "How about that local sports team." Now, think of that attitude carried over to every aspect of life. The effects of this phenomenon have been best described by Bill Simmons as the demise of home-field advantage, and it is ugly in its enforced blandness.
The corporatization of everything has turned its participants into corporate drones themselves; look at Tony Romo or Alex Rodriguez listlessly droning at their lockers. The alphas of our society have been reduced to the level of mimics blandly reciting platitudes like PR flacks, rather than going off half cocked as their more "colorful" predecessors may have once done. America is all about energy, but too often it has allowed this vitality to be sucked away in favor of some HR department-style of discourse. If the Crash of '08 and the Great Recession of '09 bring about a return of a more untrammeled popular culture (sans vulgarity, of course), that would be a positive.
