You're off base here for what may be a rather subtle reason. While I am not a marxist, I do think that the purchasing behavior of the wealthy makes much more sense when you think about things in terms of the labor theory of value.

The evidence for this is all around us. As automation of manufacturing has brought former luxuries into reach for middle-class families, those with means move on to consuming items that require more and more labor to produce. "Handmade" scented soaps. "Artisanal" cheeses. Nobody with money wants their wedding invitation to arrive at a destination with machine-canceled postage. It's tacky. Too automated, too efficient. In fact, I bet the ultra-wealthy don't even use postal mail for delivering their invitations, because it's not labor-intensive enough to be tasteful. Private couriers are probably the move. You can see this pattern over and over again once you know what to look for.

There will always be a demand for human labor, because value is a human construction. That said, the rate at which the economy will change because of AI (if the True Believers are to be believed) is probably too fast for most workers to adapt, so you may not be entirely wrong in your conclusion depending on how thing shake out, but the way you got there is bogus imo.
