I didn't mean that dollar stores had moved down market; I meant that dollar stores moved in, split the low end of the market out of the old "regular grocery store" and now the medium grocery buyer is left with the choice of dollar store groceries or some kind of grocery delivery service/meal kit/personal chef.

If this doesn't make sense, maybe it's a metaphor. Does it seem like the normal way of doing things from 20 years ago has now been replaced with an absolute garbage version, and a version you can't afford?

It makes sense to me, and it's a phenomenon I've noticed myself. Now that I think about it, though, I can't come up with any good examples off the top of my head where the middle of the market has truly been abandoned.

In tech, Apple comfortably occupies the premium end of the market, and other companies tried to move in (think Microsoft with the Surface) but with fairly limited success. With cars, the move has been to bigger, more luxurious vehicles, but you still have lower end models at various levels of trim. I have noticed it with, say, dentists, where sole traders and small businesses have essentially been replaced by franchises. Same for chemists.

To me the driving factor is that not everyone can compete on price, and competing for the luxury segment of the market is a fairly obvious alternative strategy. It also goes hand-in-hand with other factors like sustainability, where it might be impossible to make your product cheaply because you source local or recycled materials, or you make a product that is designed to last longer, so your customers don't return to buy your product as frequently.

I'd say the last 7-8 years I've noticed a move to luxury products in most markets just as a general trend. I call it the affordable luxury phenomenon. But I think a lot of it has been driven by cheap credit, and luxury goods makers reaching down into the middle market (the aspirational market) as much as the middle market being abandoned.

No, it does not feel like that to me as far as grocery stores are concerned. (My experience is in large Texas cities.)

Do you not just have some store like Tom Thumb, Randall’s, Albertsons, Krogers, Sprouts, or H‑E‑B near you? I know there are places that don’t have good access to regular grocery stores, wondering if that’s the case for you or for some reason you see these as either too junky or too high end?

For sure there are more self checkout lanes, but it’s usually not too hard to find a regular staffed lane if that’s what you want.
