What I described is a way of teaching kids to be entrepeneurial. Mixing that with "share everything" doesn't exactly work.
However if your wife and you both shared the attitude that my aunt and uncle have, I'll bet your juvenile delinquents would have turned out to be different people. I'm not saying that they wouldn't have turned out to be juvenile delinquents - I don't know about my cousins, but my brother who lived with that family for a while still wound up in a car theft ring. But they would be different. (Note: that brother also wound up running several successful businesses later in life. Coincidence?)
Cheers,
