I haven't seen the show but the "rich enough that their boat purchases are limited by channel depth and not money" level of rich people are mostly just normal people, the entire spectrum of good and bad is represented. There's less petty drama and Karen behavior because they can pay those problems away.

Source: former employment had me dealing with them, mostly subsequent generations, not the actual people who struck it rich personally.

Edit: They've all had bajillion dollar educations so on some level they're not stupid which means they can be reasoned with but the catch is that they can reason back at you.
