The wealth gap fundamentally comes down to deal architecture and financial discipline. Dempsey's 1926 Tunney fight generated $2.6M in gate receipts alone—that's a single event revenue stream that Ruth never captured at that scale. Boxing matches had a built-in scarcity model: one night, one winner, massive purses. Baseball was seasonal and reliant on salary caps set by owners. Ruth earned through salary ($80k+/year was elite), endorsements, and barnstorming tours, but he was constrained by the reserve clause and owner control. Dempsey, by contrast, could command 50-50 gate splits with promoters, controlled his narrative around mega-events, and negotiated directly with film studios and sponsors without an institutional middleman. The infrastructure of boxing money in the 1920s simply favored the fighter more than baseball favored the player.

Ruth's kryptonite was his spending. The Sultan of Swat made an estimated $8M but spent nearly as much—he was the 1920s version of a broke athlete stereotype, just with a slightly better ending than most. Dempsey, conversely, was ruthlessly financial. He didn't just fight; he leveraged his fame into real estate deals, restaurant ownership, and strategic endorsement partnerships that compounded wealth beyond fight purses. Ruth monetized his legend year-to-year. Dempsey monetized it as a brand with multiple revenue streams and lasting equity. One was a talented spender; the other was a wealth accumulator.

The final wild card: promotional genius. Dempsey's fight with Tunney was sold as 'The Battle of the Century'—it created FOMO before FOMO existed. He understood that scarcity and narrative drive valuation. Ruth was transcendent but passive; he showed up, crushed home runs, signed autographs. Dempsey *created events* that the public felt compelled to witness. That difference between being a phenomenon and being a promoter is worth roughly $177M.
