There are plenty of problems with the economics of this game. 11 home games to 12 financial updates every season, away games affect on the following game, the ability to successfully tank, making less money in the 3rd game of the finals series because you lost the 2nd on the road (i know that falls into a previously stated category but it pisses me off), the salaries of the best players in the game, etc...
There is a reason why the transfer list has degraded into the crap hole that it is. Obviously we have problems with the economy of this game. Most people can see this. However, there is a reason why things won't change...the BB's are arrogant enough to think things are perfect and that nothing is currently wrong with the economic state of this game or with how teams make/lose money in certain situations. It's idiotic, but it won't change. It's a pity...
Arrogant or not, it's clear from a business standpoint that the BBs must assuage their user base or their customers will leave. And right now, it seems like the paying customers are complaining the loudest. While Charles' claim that tanking is a sup-optimal choice may in fact be true, the
perception of a lot of users is that tanking is an economically viable choice. Raising the salary floor and punishing teams more severely for massive blowouts would go a long way towards fixing this problem in the eyes of many users. Wolph has some good ideas above for tweaking attendance.
There's no easy fix to the salary issue. Drastically decreasing the salaries of top players would widen the gap between upper and lower division teams, as the increased affordability of these players would drive transfer prices up, making it nearly impossible for teams without a stockpile of money to purchase them.
The 12 economic updates/11 home games is a non-issue for me. The Cup more than makes up for the economic difference and I think it adds a bit of strategy to the game.
