Doing the millionaire scenario

I play rags to riches all the time, but I never tried to make my Sims millionaires because even at a 100k, they'll never really run out of money. A million is just a ridiculous and useless amount of money in this game. However, I am tempted to try this scenario with a Sim I created years ago. I'd probably go with the Fabulously Wealthy aspiration to get the investment pay outs and make them go the celebrity route to get the Easy Street perk. Otherwise a million is hard to achieve in a Sim's lifetime without money trees and/or painting, I would imagine.
