The very best decision the Dodgers GM made was decide "we are going to use our resources to be the very best team at talent development". Before the Dodgers, the big markets weren't really considerably better if better at all at developing talent than plenty of small markets. I'd argue the mid-market Cardinals were probably one of the top teams at developing players up until maybe 5 years ago. The Dodgers pipeline is so insane, they can trade 2-3 top prospects every deadline and a couple more pop up the next year. And generally they are smart enough at identifying talent to keep the very best players and add them to their loaded roster(Bellinger, Seager, Smith, Lux, Buehler, Urias, May) while trading the guys they don't think will establish in the end. It's honestly a bit disheartening because as long as the pipeline keeps going, along with having more money than Bezos, there's really no reason the Dodgers shouldn't always be one of the very best teams in baseball.
