Just stumbled on something wild - been looking at how much money U.S. presidents actually had before and after their time in office. The wealth swings are insane. Like, some guys came in rich and left broke (Thomas Jefferson went from $3M to basically nothing), while others doubled down. Obama's net worth before and after presidency is a perfect example - went from $1.3M to around $70M. That's the kind of wealth trajectory people don't really talk about. JFK was already sitting on $1B, so presidency didn't change much for him. But look at LBJ - started with $20M and walked away with $100M. Then you got guys like Grant who went the opposite direction, lost almost everything. Honestly makes you wonder what the real ROI on being president actually is. Some left richer, some left poorer. Obama net worth before and after presidency shows how lucrative the post-presidency life can be for some - speaking deals, books, that whole ecosystem. Trump's another wild case, went from $3B down to $2.5B. The data's pretty eye-opening when you lay it all out like this.
