Hillary Clinton has recently come under fire for stating that she and her husband, former president Bill Clinton, were "dead broke" upon leaving the White House, with critics saying that such a statement was out of touch with the real world and the average American.

While it would seem that Americans tend to distrust wealthy politicians and seek presidents who can relate to them financially, historically the U.S. has elected presidents from a wide range of economic backgrounds. Abraham Lincoln may have had an adjusted net worth of less than $1 million, but one of his successors has been valued at upwards of 1 billion dollars.

This list features the 15 richest U.S. presidents at the peak of their financial success, in or out of office, with net worth adjusted to fit today's economy and monetary values. Facts and totals have been taken from TIME and The Atlantic.
