fans cope because those clubs are apart of the community. They are usually started by locals and work their way up the footballing divisions.
In America, its the exact opposite. Rich people come in and say "we are putting this franchise here!" They put it there and then they decide to move if they are not getting their return. That is very difficult to do in soccer where these clubs were started by the community they are in and people are invested in it.
City and the Rangers do not compare because they came up in an entirely different fashion. On August 30th, 2008, Manchester City had an owner who's money was frozen because the country he was president on were charging him for corruption and were a decent club but not a big time player for the world's biggest talents. Literally the next day, a Sheikh from Qatar come in and change everything. Making massive bids for top players around the world and getting one from Real Madrid and going from there. The next year they spent even more money, and its been like that since that day in 2008.
The Rangers and Angels both were surprise teams when they started making headway. City are not a surprise, it was more or less expected.
