> But it appears to me that this market is highly regulated - safety, fuel efficiency and longevity still hit the bare minimum, just the legal minima have been tightened over the years.

That's just because customers want something different. If the law requires 25 MPG and the carmakers can either give you a smaller, slower car that gets 60 MPG or a bigger, faster car that gets 25 MPG, lots of people pick the second one. Then you say they're barely meeting the minimum fuel efficiency but really the customer is the one making the trade off.

> Passenger air travel - you must be traveling first-class only to not notice that everything below is bottom-tier and getting noticeably worse every year. Sure, it's more affordable - I don't dispute that - but it's a question of how bad can quality go before it trumps price.

Air travel is a really weird market because the capital investment is huge but the market is fairly competitive, which is a recipe for bankruptcies. Make a bad prediction about customer demand or future fuel costs and you're not making enough to pay back the bank. Then they have to get creative or go out of business.

They tried price fixing for a while and got in trouble. The current trend seems to be cost cutting so they can lower the price and keep the seats full. It's the same thing as the cars: Customers keep picking the one with the lowest price, so they keep finding ways to lower the price.

> Smartphones, televisions - all examples of what I'm talking about. A huge amount of bottom-tier products, a few high-end flagship products. There's a degree of market segmentation so there's still some middle-tier options, but my impression is, they're rapidly dragged to the bottom.

This, and really most of the rest of your examples, is a result of China's long-term strategy to dominate manufacturing. Which is, use profits from one industry to subsidize another one until it dominates that too.

When they enter an industry their products are crap because they don't know how to do it yet. So no one would buy them. So they subsidize the price until they're cheap enough that people do. In a normal market they'd go out of business, but the government is financing their losses, so they don't.

Which destroys the middle tier products or forces them to slash quality and compete on price, because customers would pay more for them, but not infinitely more. And the low-end junk gets subsidized until it's cheap enough that people choose it.

That doesn't really apply to real estate. Real estate is already heavily tiered by price. If the 20th percentile house in a city is $200k and the 80th percentile house is $800k there will also be plenty of everything in between. It's not like the 20th percentile house is $200k and the 75th percentile house is $210k and the 80th percentile house is $800k.

Meanwhile most of the housing is still going to be the existing housing. If they build luxury housing, affluent people will buy it. If they build tiny studios, price-sensitive people will buy it. In either case you now have those people not bidding against you for the housing that already exists.

You are also under no obligation to wait for them to build something and then take whatever they offer. You can go to a construction company, tell them what you want and have them build it for you. You can get whatever you want -- if the zoning doesn't prohibit it.
