Someone asked King Richard why he doesn't have kids:
I heard you speak of the consumption pattern in the US and you mentioned about how you developed inexpensive habits. That included children. Why?
Which does more good: spreading freedom for millions of computer users, or raising a few extra children in a world that is already suffering from an excess of them? The question answers itself. Why in the world would I do the latter, when I have the chance to do the former?
Do you believe this is the real reason?
