If you’re actually pretending the MLB has better parity than the NFL, then you simply don’t get it and it’s not worth arguing further. The KC Chiefs, Buffalo Bills, Baltimore Ravens, & Pittsburgh Steelers are all small market teams that have been incredibly successful. Does having a great QB make a massive difference in your ability to succeed in the NFL? Of course it does, but the system in place gives small and large market teams an equal chance of landing one of those players. And generally speaking, it gives all teams the same level of resources to retain talent and acquire new talent via free agency.
You seem to want to blame the lack of parity in baseball solely on the “cheap” small market owners. And yes, that factor plays some role and baseball needs a salary floor to prevent them from pocketing revenue sharing. But that doesn’t change the fact that the Dodgers & Yankees pull in significantly more revenue than their small market peers and can therefore spend considerably more than them. That is a foundational problem with baseball and again the randomness of the playoffs doesn’t change that. The big market will continue to make the playoffs more frequently than their small market brethren and they will continue to win the majority of World Series titles over time.
