See, it's this sort of shit that makes a farce of the claim that somehow there's some virtue to City cheating their way to success, because the alternative is some entrenched system of haves and have nots.
How on earth is it more just to have the arbitrary investment whims of some rich fuck decide things? As though it's ok that capitalism is not a meritocracy, because there's a lottery, or you could be taken in as the pitiable ward of some aristocrat.
Man City aren't a big club. They weren't when they didn't have money, and they still aren't now. It makes sense that they can't compete with Liverpool or United. They have no business doing so.
Why should they break in, instead of a whole mess of better supported clubs, some of which have far richer histories, and more success?
If you want every club to have some chance of victory, then you are looking at an NFL model. Neither the current model, nor random benefactors, are fair, but the former is more meritocratic, as disturbing as that might be for those on the outside. Well run clubs do have more of a chance of breaking in, even if mobility is the exception, and not the rule.
