Is Bill Gates an Oligarch?
Yes he has money... which he earned in the traditional American way. He doesn't plan to leave much of it to his kids. Bill Gates has joined Warren Buffet in pledging to GIVE AWAY the bulk of his wealth. Most of it (95%?) may very well go towards the Bill and Melinda Gates Foundation to be used for charitable causes. Have you considered the Bill and Melinda Gates Foundation and its education efforts and the work it is doing to wipe out diseases around the world?
Now tell me that he is an Oligarch.
