1) George Washington (Net worth: $525 million)

George Washington was the first president of the US. He held the office of the president between 1789 and 1797. His salary was 2 percent of the total US budget in 1789. His Virginia plantation, Mount Vernon, consisted of five separate farms on 8,000 acres of prime farmland run by more than 300 slaves.

So if you intend to run for the president, you need to work really hard and make plenty of money.
