Or you just buy stuff which is mostly zero sum, such as more real estate or more services which simply have no productivity gains to be found as they are based on time/the human being human.

You see that here in Canada and in the USA. The amount of dwelling space we occupy has soared even as families shrink. My Dad grew up with a family of 5 in 1200 sqft. Canadians today consider that a shoebox that barely fits 2.

I would bet that income gains are disproportionately directed to buying more house or additional houses, no matter the income.

Or you buy more massages or more tutoring or more other various services that simply cannot be multiplied 100x as the human is an integral part of the service rather than a stand in until the robot is ready. How does a massage therapist massage 100 people at once?
