Mane, you accounting guys don't seem to get a grip on economic concepts. forreal.
Income and salaries are stable (except for personell, those incomes are hyperinflating by design), basically it's just the amount of money circulating in the economy that is increasing. Now that we have reached a Point where the net income can only be spent on the Transfer market and millions of Promotion Money from Utopia were flooding the economy, plus we are forced to Keep Players for exceptionally Long time it had to be expected that Prices would surge, as the supply is shortened (nobody wants to sell with a huge loss).
There are many factors why this has happened and most of those came from the developers side - most of them with good intentions, but the outcome might have been a bit different than expected.
I'd suggest to do nothing and re-evaluate after next season.
