Nonsense. London is considerably wealthier than Washington DC. It is not a matter of money, it is a matter of what Americans are, and Europeans are not, willing to accept when it comes to sport.
This is what sporting culture refers to; American sides are 'franchises', marketing contrivances for the most part, which with few exceptions have no real history or connection to their communities, and which will up and leave the instant they can extort better taxpayer-subsidised rent seeking opportunities elsewhere.
It is very different here - the level of supporter passion, commitment, pride, and custodianship is beyond comparison. Obscure fifth division sides like Luton routinely draw 10,000. It wanes slightly all the time, not least in England, but supporters still do exert real impact, especially outside of the few premier league clubs that are global 'brands'.
But even supporters of Liverpool, a vastly more corporate, tourist, and Official-Malaysian-Housepaint-Partner-oriented club than we are (thank the heavens), forced their American hedge-fund owners to back down the last time they tried even a whiff of the nonsense the article I posted describes.
