Dear God, man! You think it's a good idea to have 4 year olds deal with the screwed up machine-like law system we have in place? Let them have at least some liberty and dreams before they turn 16 and start getting arrested and thinking of anarchy or suicide... oh wait, that was a sarcastic comment, wasn't it?
4 year olds buying flats from Costco and setting up a concession stand at a fair? This isn't kids playing and having a good time at home, this is running an apparently legitimate business, which should be run actually legitimately.
