We already live in a Plutonomy. Already 50% of sales in USA is by the top 10%. The top 1% make most of their money selling to the top 10%. The Elites don't need us for consumption to make money. Walmart is reconfiguring their sales model to carry more "luxury” items. And now with AI the Wealthy wont need human labor hardly at all. We are surplus to requirements.
The sad thing is it doesn't have to be like this. AI could be used to reduce peoples working hours and give them more leisure hours.
