Sean Parker – #7
At the age of 31, Sean Parker became the first president of the largest social media service in the world known as Facebook. He also co-founded the file sharing service Napster. This 34-year-old is one of the richest entrepreneurs in the world with a net worth of $2.1 billion.
As an industrious high school student Sean Parker interned for some powerful people, reportedly worked on projects for the CIA, and was earning more than $80,000 a year by the time he graduated from high school. Like many other billionaires, Parker did not graduate from college.
Parker devotes much of his personal time and wealth to many charitable causes, as well as founding some charities of his own. While many wealthy people contribute to social causes for the tax breaks that are earned, Parker claims to be doing so for purely philanthropic reasons. In recent years he has spoken in favor of levying higher taxes on the wealthy.
