I'm in e-commerce and this has been going on for decades, in physical retail too. 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.
