AI will crash the price of manufactured goods. Since all prices are relative, the price of rivalrous goods will rise. A car will be cheap. A lakeside cabin will be cheap. A cottage in the Hamptons will be expensive. Superbowl tickets will be a billion dollars each.

What does a middle class family spend its money on? You don't need a house within an easy commute of your job, because you won't have one. You don't need a house in a good school district, because there's no point in going to school. No need for the red queen's race of extracurriculars that look good on a college application, or to put money in a "college fund", because college won't exist either.
The point of AI isn't that it's going to blow up some of the social order, but that it's going to blow up the whole thing.
