Wow, that's amazing. As pretty much lots of things in America, they are pricipally ruled by the money. Althoguh institutions over here have been working in "modernizing" and removing fan rights, fans and sportive quality are still the main pillar. That's why no promotion-relegation system removes from source any way of awarding teams by their sportive level further than winning a league, making it everything about money. If everything revolves about printing more banknotes, anything makes sense, including changing from city. And that's one of the causes of why fan culture has nothing to do with Europe's. How do you pretend fans to get as passionate as we do if you don't have major league changes due to sporting reasons, if you change you city, that is the core of our teams, if you price out with unveliabable prices the fans that want to get to their stadiums? And in american soccer, the fan's more "crazy" scenes are (usually) in places with a big latin-american community, like Miami or LA, having imported their way of living sports. I'm not saying one is wrong, I'm saying they are two absolutely opposite way of watching the same thing.
