Peter Frase wrote an article (and soon after a book expansion of it) called "Four Futures" in which he examines this question.

According to Frase, the future we wind up with can be categorized into a Punnett square based on two questions: will essentials be abundant or scarce? And will they be distributed selfishly or universally?

If we have more than we need and we give it away universally, that's Communism. If we have less than we need, but we share what we have and our burdens equally, that's Socialism.

Now here's the two you're asking about. If we don't have a populist revolution, we wind up with one of the bad ones.

If we have abundance, but it's hoarded, we get Rentism. You can see outlines of this already. It's where you pay for digital files that can be endlessly reproduced and are forced into subscriptions to continue using appliances despite the fact that their continued use is free to the company. This is the one you're asking about. If we reached full automation, but still charged people for everything, you'd have a version of serfdom, likely with a basic income. The income would likely be based on a social credit system in which people who show the most obedience are rewarded with money to buy things that are basically free to produce. There might be a system of artificial scarcity to force people to devote a certain number of hours each day to unnecessary work or watching advertisements to receive income.

The last one is called Exterminism. You can read about it in the article. It's pretty self-explanatory.
