MLB profits aren’t shared. But if they were losing money, teams wouldn’t go up in value every year. They wouldn’t be sold at increasingly higher values every single time a team hits the market. These are big profitable monopolies.
With the Nats, there are constraints, like paying out initial investors. But they have never operated at a loss outside of maybe 2020.
People with any sympathy toward owners should read Lord of the Realms for a primer and dig into the business of baseball a bit more. This isn’t billionaires vs millionaires, this is corrupt owners squeezing everything they can out of their monopoly at the expense of minor leaguers, short-tenured players that can’t negotiate their salary, and the American public.
