He is a businessman to where profit rules best. He made $2 billion off of $230 mil by signing Pujols and using him to up the ante from Fox Sports West network TV. Also, it includes broadcasting it via radio to latin American stations. It's the best billboard sale he's every fallen into. If Arte wants to compete for the playoffs with the current setup of his design, then he needs to go over the luxury tax to get pitchers. But that would be losing profit, which is why he doesn't and why the Angels have no prominent pitchers.
The other aspect to Arte is that he wants his finger all over the baseball team. This goes away from efficient baseball construction, but not necessarily profit margin. Arte prefers long ball hitters to draw in fans. Arte already had Trout when he bought the team. Then he added several sluggers such as Pujols, Hamilton, Upton, Ohtani, and Rendon. The org lost two consecutive first round picks by signing FA's Pujols and Hamiltion when the rules were different back then. We didn't lose a first round pick for Rendon. Arte won't relinquish baseball operations to the baseball people, which is why Dipoto quit and why newest GM Minasian drafted 20 pitchers with the first 20 draft picks in this last draft.
Getting Arte to step away from baseball operations will the hardest thing for him to do and what's been holding the Angels back. Arte is raking in billions by owning the Angels and doesn't care how they perform because he's breaking even or making a profit still. When the team doesn't perform, then it's never his meddlesome efforts, which is why we are cycling through GM's.
