George W. Bush
Just like his father, George W Bush had a mind of a businessman before being the senator of Texas or becoming president. He had an oil business from which he made a small fortune and was the owner of a professional baseball team called the Texas Rangers.
By the time he entered the presidential office, he had a higher worth than any other modern president (except for Donald Trump). By the time he finished his mandate, his worth had doubled, mostly the way it did for the rest of the presidents as well: from speaking fees.
Summary: Before being president, George W Bush’s net worth was $20 million. After his mandate finished, his worth doubled.
