Just scrolled through some data on how U.S. presidents' wealth changed during their time in office and it's pretty wild. Some made bank, others actually lost money.

Take Bill Clinton - he went from around $1.3M before presidency to roughly $80M after. That's a massive jump. Obama had a similar trajectory, climbing from $1.3M to $70M. Meanwhile, Trump actually dipped slightly from $3B to $2.5B, though he still stayed in billionaire territory.

But here's the interesting part - earlier presidents tell a different story. Thomas Jefferson started with $3M and ended with just $200K. James Monroe went from $1M down to basically nothing ($50K). Even Ulysses S. Grant lost huge amounts, dropping from $1M to $80K.

The wealth changes before and after presidency really vary depending on the era. Some presidents clearly profited from their time in office, while others faced financial difficulties. The Bill Clinton net worth trajectory before and after presidency is one of the most dramatic examples in modern times - that $80M endpoint is wild compared to where he started.
