The problem is not the FA, but the BBs who dont have a clue how economics work.
The market prices are not stable over time, right now they're decreasing again.
First they introduced Utopia, which had a huge impace on the market prices (they increased a lot at the beginning, and then started decreasing after a while).
Then they introduced the "hoarding tax" which again had a huge impact on the market prices, because every rich club started spending money. So again the prices went up (some players were sold for $>5 million) and are now decreasing since then...
