I then asked students to think about why someone such as Bill Gates contin¬ues to work. The day I write this, Fortune announced its 1999 estimate of Gates's fortune at more than $90 billion. Surely this is enough wealth to do whatever he wants, yet he continues to work full-time for Microsoft. Why? To the cynic who suggests that Gates works only to continually increase his wealth, I point out that Gates (as virtually all people of enormous wealth do) gives away signifi-cant amounts of money. If financial greed was his only motivation for working, he could stop giving his money away and work less.
