The Dodgers are smart, but the super smart Brewers can't go out and drop 700m to get the greatest player of all-time plus anyone else available they fancy. They can't line their rotation with 5 Cy Young-caliber SP's and get more if some get hurt plus grab a bunch of HOF/elite caliber hiters whenever they want. It's a joke.
The greater LA area is almost as large as the greater NYC area, almost 20m people, and almost twice as big as the greater Chicago population. So LA is among the top 2 US markets by a very large margin, plus being able to buy Ohtani and Yamamoto etc means their market extends to Japan's 120m people.
Yes it also takes smarts and some luck, the Mets/Angels prove that, but not every team can dominate like those markets allow. The Brewers have never won 100 games in a season ever. The Dodgers have done it 6 of the last 9 years if you count 2020 and on pace for 7 of 10 this season The Brewers have also never won a ring.
