According to a list of the richest people on the planet, Bill Gates, co-founder of Microsoft, is the king of the hill. Forbes' list estimates Gates has a net worth of $75 billion ($76.5 billion as of 3/3/2016). While no longer a major presence at Microsoft, Gates has turned his attention to solving the world's health problems in developing countries with the Bill & Melinda Gates Foundation.
Another list released earlier this year put Gates as the richest person on the planet with an estimated net worth of $87.4 billion. Either way, Gates is still earning well beyond what your typical college dropout or even college graduate would ever earn in their lifetime, and he is putting his money to good use by helping others through the Gates Foundation.
In comparison, Microsoft's other co-founder, Paul Allen, has a mere 17.5 billion, ranked as the 40th richest person in the world list ($17.6 billion as of 3/3/2016). Gates has been the richest person on the planet for 15 of the last 20 years, and it doesn't look like he will be giving up the spot anytime soon. Forbes estimates that there are more than 1600 billionaires around the world.
