They won't do it because part of the reason for the current corruption is brand image. They need to do everything imaginable to make sure that at least 3 of the big 6 (RS, Utd, Arsenal) are never in any danger of dropping away. Hurts the brand. Chelsea and City, i think they were begrudgingly allowed in to the club because of the sheer amount of money they have had, and Spurs are there because they just happen to be there. If it wasn't them, but they were replaced by Newcastle or Villa, they wouldn't care either way. If it was us, they would not be happy.
So the important thing is that those big 3 are looked after and front and centre. If they weren't, the rules would change overnight.
In an ideal world, if they wanted true parity and competitiveness (they don't), then all clubs would have a set budget and wage structure. If 1 team decided to forgo 5 players in a squad to give 1 player a massive wage, then so be it, but it's then their choice.
But regardless of how badly we have mismanaged our position, and we have, a league that penalises a team for overspending in a bid to bridge a gap, an overspend not based on a pre applied league limit, but instead based entirely on individual turnover, when the total 3 year rolling overspend is close to the annual wage of 1 player at another club, cannot be anything but corrupt. Its anti-competitive.
Which is exactly the way they want it.
P. S. I don't want to hear anything about how Brighton have managed it. Brighton are not Everton. Their expectations and reputation are not Everton's. Their approach to transfers is entirely different because it can be. If we had tried signing some of the great finds Brighton have, we would've paid more than Brighton did, because the selling clubs and agents would insist upon it. Brighton may find the same thing happening to them soon enough, if they continue to overperform.
