I don't see that very appealing from a players point of view, going on two weeks vacation and coming back to find I have lost a nice chunk of money.

EDIT: If your going to be giving money from the bank, as well as taxing the money, Unless your taxes are higher than your paycheck, your going to need a way to bring in money to keep the economy flourishing but not so much as to inflate it.
