I don't think this is true. At all. The Dodgers have an $100 million per year head start on every other team in the league via their tv deal, the Cubs are far from poor but they don’t have a structural advantage that approaches it. https://blogs.fangraphs.com/lets-update-the-estimated-local-tv-revenue-for-mlb-teams/ Instead of comparing them to the Dodgers or the Yankees/Mets, why don't we compare them to the Phillies, Padres, Blue Jays, Angels, Braves, Astros, and the Rangers. They certainly have the funds to outspend these teams.
