There are already a lot of good suggestions here!

I would add Eat the rich and The menu (not related) for movies criticizing the rich. Although the former just makes fun of them.

I would also argue for Andor even though it doesn’t focus on the super rich and instead on the rebellion and the people making up the cogs of the fascist imperium. It still shows the rich in a critical light. I haven’t seen any series that made me want to fight the system more than Andor.
