> the "rent-seeking class" that has effectively existed for thousands of years

This "rent seeking class" is not a historical universal, regardless of how much college marxists insist that it is. Leaders can be good or bad, and they hold power in different ways. In America today we have bad leaders (across the entirety of the political spectrum) - and AI poses a lot of challenges in how they hold power. This is not to say Chinese leaders are any better - but the way they hold power is not challenged by AI. Business models will indeed adapt - but the condition is excellent, as they say.
