The wealth gap boils down to business model brutality: Rockefeller controlled 90% of U.S. oil refining and pulled in $90M annually during the early 1900s—that's recurring, compounding, almost passive income from an actual monopoly. Roosevelt inherited maybe $10M, which adjusted to $365M sounds impressive until you realize it's a one-time lump sum that he hemorrhaged on hunting expeditions, conservation projects, and political ambitions. Rockefeller was a wealth-accumulation machine; Roosevelt was a wealth-consumption machine wrapped in a Rough Rider outfit.

Here's the brutal part: Rockefeller's antitrust breakup actually *made him richer* because his remaining Standard Oil shares continued printing money for decades while he literally just held them. Roosevelt's inherited wealth had an expiration date because he treated money like a renewable resource. He was President making $50K/year while simultaneously funding his own conservation initiatives and writing books to stay afloat. Rockefeller could've been comatose and still gotten richer; Roosevelt had to *work* to avoid bankruptcy despite starting with serious capital.

The real difference is optionality: Rockefeller's wealth was a closed loop that fed itself—more oil refined = more profits = more capital to dominate the market further. Roosevelt's wealth was an open sieve—every dollar he touched was earmarked for his next big idea, his next political move, his next safari. One built a machine that prints money. The other inherited a trust fund and used it to change geopolitics. Guess which strategy leaves you with more actual dollars?
