This is not specific to Bill gates. I read some where "Bill Gates !something! $43billion. (!something! -I'm not sure what the sentence was). Does Bill have $43 in cash( like not his company) and he can go spending all his 43 without any problem and does not need to sell any of his company to spend his 43. Why I ask this is becoz google is valued at 80billion. So the owners of google should be the richest right?
