I have to disagree with the inflation statement.
The value of money has indeed gone up and down throughout time in BB. At one point crappy players that are selling for 100k now were sold for 500k and it wasn't abnormal to see players sell for +3million either.
Now days people have way less money unless they started back when players were sold for a lot and they saved their money.
Also,with the second teams starting we will probably see player prices go up slowly over the next couple seasons. So a bank could be a good idea to compensate for the growing prices of players and staff. Probably won't happen but it could be a good idea.
