I think you know me well enough, and have hopefully seen my numerous defences of City re FFP to know I am not anti-City. My defences are not based on being pro City either, more they just reflect that it looks and feels anti-competitive.
However I do understand the thinking behind why some chairman wanted some action. While in general my view is shareholder investment and money into the game is a good thing, it has created a prolonged bull market in the PL. You can understand why certain owners wanted to try and limit the inflationary pressures that had followed Chelsea's takeover.
I also think, with Everton we were in quite a unique situation. We had sort of fought our way to being 5th in the league, the "best of the rest" which had taken 5+ years of steady work. The summer you signed Lescott from us, after he was our best player and had formed a very solid partnership with Jagielka, having finished about 12th or whatever the previous year was quite painful. It wasn't really City's fault, it was more a reflection of a number of factors but it seemed symbolic of everything that seemed wrong for ourselves. We had fought our way up, wut next to no money, developed this team and players, and you could sense City were just going to take what seemed like "our" spot. I don't really think Hughes helped with some of his comments and carrying on as if City were somehow ahead of Everton.
The reality is though, I'm not sure you can legislate to prevent such occurences. I also think as a football club, however painful it was, selling better players for a decent premium (as we did with Lescott, Fellaini and Rodwell, and what we should have done with Rooney and Arteta) was a great opportunity for us. The signings of Heitinga and Distin covered what Lescott gave us, and we kicked on again.
The other point is that I'm not sure anyone can legislate to prevent that sort of move from a club. However, even though legislation worked, you also felt it was a particularly badly drafted peice of legislation. It offered clubs like Everton hope, but in honesty they had little interest in protecting us, and soon people fell out of love with it. Lots of people painted what they wanted onto FFP, but no single peice of legislation can be all things to all people.
