There's a wider breadth of quality among American mass-produced beers than there was when we were growing up. Shiner Bock and Yuengling are pretty damned good. I don't think Abita qualifies as a micro-brewery anymore. And I do like Fat Tire. OTOH, there's always Natty Bo we can throw rocks at.Other than small house or craft beers, I can't see how most folks can drink standard American swill and pronounce it worthy.
I lived in Germany - then West Germany - for six and a half years, courtesy of my rich Uncle. German beer fully deserves its reputation. But the move in the US to regional breweries has resulted in a huge narrowing of the quality gap between German and American beers.
I haven't thought of Ballentine and Piels...or Rheingold... in ages. When I was of beer-drinking age the cool stuff was Genny Cream Ale.
ETA: I'm going to get a sixer of PBR tonight, for explicitly cultural reasons.
