These things are much more complex than simplistic single-variable models.
It is not actually more complex, you don't spend ~40% of CPI on apparel.
Much of what you can buy today did not even exist 30 years ago. For example, trail running shoes more or less did not exist. Perhaps you could have had a pair custom made, at a high price, with the worse materials available at the time, but today you can them "off the shelf".
Even the many shirts I've received for free are very high quality and have endured years of abuse.
Do you have a source for this? Anecdotes along the lines of "they don't make 'em like they used to" are incredibly common but often fail to stand up to scrutiny.
Like yes a nice pair of boots costs more and you do get more value out of them compared to Amazon basics boots.. but far more people end up buying the cheap option because it's cheap and available.
Some regulations are bad. Some regulations are good.
The abundance types do not want to remove good regulations, like structural integrity or fire safety regs.
They want to remove bad regulations, like parking minimums or building height limits.
Please understand this very important distinction.
My town has a bunch of half empty new buildings that are keeping their prices high instead of competing on price (they're also garbage construction, so they didn't compete on quality either). Apparently it makes more financial sense to the owner to keep empty units instead of competing because of the value of snagging a few tenants at higher rents or something.
Not only that, but the walls/floors were paper thin. We could hear the floor creak when our upstairs neighbors so much as shifted their weight.
Inflated building code is a great way to repress the rate of new construction, and if it's all in the name of safety or energy conservation, no one can stop it, even if it's entirely useless for your house. That leaves low quality materials as the only ones affordable for a starter house.
The last hurricane I survived, I had to spend time in my office building. It is made of concrete and real brick and mortar. There is no need whatsoever to “hurricane-proof it", save for the special shatterproof windows. Big, 4 by 6 shatterproof windows.
The shoebox I live in currently features the same shatterproof windows. 2x1 feet, small windows. I had to re-install all the light fixtures in the rented house because despite featuring white walls, it’s darker than a necromancer’s cave.
The former was built in the 70s. The latter - in 2023. The latter does boast an impressive array of anti-hurricane features. For example, it is bolted down to the foundation so it can't be torn by a wind gust. And the frame was re-inforced so it won't lean under the wind.
Shall I mention the fact that none of those features are necessary for a brick building?
To top it off, the AC has leaked in 2024, so I had to deal with that already. It was less than 1 year old at that moment.
Recently I've visited a rental property to find shallow, not sound-proofed walls, askew doors made of something that looks like paper and not a single straight corner. And this is a 2023 build! It's brand new. And still looks awful.
I have an article about that. https://medium.com/@ifcllc/qualification-f33ec8fcb736 but man, it's getting worse and worse.
Just to have a 2-room apartment that I used to live in 30 years ago would cost over 1.5 mil today. Adjusted for that inflation of quality.
