This discussion has been superb -- it is a pleasure to be competing with people who are capable of bringing this sort of understanding / analysis to the game.
I understand the problem to be one of compensating with an extraordinary windfall those teams who are already blessed. It's as though the government were to suddenly place a cap on housing prices and forced the richest to sell their homes -- but at the price they paid for it. So Bill Gates gets his 100 million back, free to spend, while suffering the indignities of having to live like the rest of us.
My team is not rich and has never been but some seasons ago I decided to invest in Arena and Trainees. Since I couldn't spend more than I had I did not invest in mature players. With 18.600 seats my Arena isn't huge but among the larger ones in my division level (II. in Germany).
Now the thing is: I do not feel blessed at all. The changes in Arena and team funding (TV, Merchandise) bless those teams that had chosen to spend the same amounts of money in mature (expensive) players. Given the available information before the changes they had done a bad investment and were close to being bankrupt.
Comparing the two choices the teams buying expensive players with wages too high to be paid are now in favor, because the changes adapt to their strategy. I get my money back, so what? With better(but in reality unaffordable) players my team would have had the chance for one promotion more.
My point is: having a larger arena has been a choice as well as overbuying players. Both has been a fair and reasonable choice and did cost the same money. Do not reduce it to a rich/not-rich discussion and look at the extremes only.
