Parents mad at University Sims for cooking and showering at home.This is inappropriate, please stop!

Do you know what my brother does when his Sims need more money? He goes into household manager, moves his Sims into the house of some npc Sims; then he moves them out and takes all their money. Then he moves them into another npc household, and does the same thing. He can easily make his new Sims rich super fast.

I haven't done that though. I like my Sims to make their own money (or move in with their friends).
