What do you do with your Simoleons?

My sims start out really struggling because of different mods I have in place. Eventually, after paying off multiple loans, they start to get back on their feet quick if it's a large enough household. I use those funds to buy expensive cars so each sim doesn't have to pay taxi fees anymore and if they move out, they'll have wheels. Also helps balance out the money... but I have been known to use familyfunds cheat just to take away money if their earning too much.

I guess I'm kinda strange... I like to see my sims struggle financially which is pretty darn cruel. This is interesting to see all of the different play styles here. :)
