What do you do when your Sim(s) are stinking rich?

Like a lot of people here, I handle it by using a vault and letting bills do the rest. Otherwise, the Mansion Baron aspiration will use up a few thousand grand to do. You can also just have sims try not to make money - earning skills through books or whatever (and quitting jobs). Continually having services such as a caterer on the lot could help too (in the long run). If all else fails and it becomes too annoying, just cheat the money down :lol:
