Lawrence: Well you don't need a million dollars to do nothing, man. Just take a look at my cousin, he's broke, don't do shit.

It's a great idea when your children are young, but they are in their fifties now...

The British entrepreneur and investor Peter Jones also worried about that problem and decided to double any money his children earned for themselves.

I don't like that as an incentive. For a start, it keeps your children in your financial orbit for the rest of your life. Secondly, it communicates to your children that you don't expect them ever to make as much money as you did.

Whenever I wish I were super-wealthy, I try to remember that super wealth probably just creates all sorts of problems when raising children. If I ever do get super wealthy I'll plan to spend all but a few million dollars, secretly and out of sight of the children, before they reach the age of twelve, so that I don't have to worry about them growing up with the typical rich-kid problems.

He's actually even more tactical than that. The multiple depended on the job his kids get. I think he said he'd quadruple a nurses salary but they wouldn't get anything at all if they became investment bankers.
