Bill Gates earn US$250 every SECOND, that's about US$20 Million a DAY and US$7.8 Billion a YEAR!
If he drop a thousand dollar, he won't even bother to pick it up coz by the 4 second he pick it, he already earn it back.
US's national debt is about 5.62 trillion, if Bill Gates will pay the debt by himself; he will finish it in less then 10 years.
He can donate US$15 to everyone on earth but still left US$5 Million for his pocket money.
Michael Jordan is the highest paid athlete in US. If he don't drink and eat, and keep his annual income US$30 Million up, he'll have to wait for 277 years to become as rich as Bill Gates now.
If Bill Gates is a country, he is the 37th richest country on earth, or US 13th biggest company, even bigger then IBM.
If exchange all Bill Gate's money to US$1, you can make a road from earth to moon, 14 times back and forth. But you have to make that road non-stop for 1,400 years, and use a total of 713 BOEING 747 plane to transport all the money.
Bill Gates is 40 this year. If we assume that he still can live for 35 years, he has to spend US$6.78 Million per day to finish his money before he dies.
BUT!!! If Microsoft Windows' users can claim US$1 for every time their computers hang because of Microsoft Windows, Bill Gates will bankrupt in 3 years!
