Companies don't serve poor people; they have no money. Companies will pivot to serving the people who have money. If that means they only serve rich people, then that means we'll have more yacht makers and fewer dollar stores.
The trend is called "retail polarisation".
Smaller retailers switch to targeting wealthier customers - higher margins and less bullshit.
The less wealthy customers then get served by ultra-value megabrands like Temu/Shein or Kmart/Walmart, or second hand marketplaces.
The net result is both more yacht makers and more dollar stores, but less mid-range stores like Target or Toys R Us.
Right now they're going on ~5-10 superyachets each. I could see them buying 100 in the future after they're 100x as rich. I think 5-10 which are 100x larger would also count for these purposes.
For car collection people will keep going well into the hundreds. Hell Jay Leno just did a video with Joe Biden yet again and his corvette, but Jay Leno famously has hundreds of cars.
And the AI revolution is no housing, worsening food, a few people with yachts, the Epstein class getting away with what they want to do, and no new plumbing hookups because the datacenter took the municipal water supply.
