I can't wait for the day when I can walk to my local dump and move into a mcmansion somebody threw out because the paint was the wrong color... And I am only half joking. Go into your local thrift store and try not to gasp as you walk past $300 pair of designer jeans after $400 dress, some of them still with tags on them as they've never been worn, and most all of them in seemingly brand-new condition. It's a consume…
The thing is, I'm not the one buying the items usually. They're gifts. And it doesn't matter how many times I tell family not to buy this or that, they do. Christmas is crazy, I hate it for all the wasted money and excess things to deal with. I hate my in laws showing up with well made furniture that I nevertheless hate the design of and don't need. I hate being the caretaker of other people's anxiety manifest in things.
Also, I have little time. So when clothing nmanufacturers do stupid sizing things to save a buck, and it doesn't fit me even after trying to get a tailor to fix it, I'm done spending time on it. It might fit someone else.
I've learned ironically used things on eBay often fit me better because the particular item's exact measurements are provided. I don't have to guess what "medium" means, or whether or not a 27.5 in length actually means 27.5 inches.
I guess my general point is a lot of these excesses are actually about inefficiency and broader societal norms. Even when you have someone who just wants a few nice fitting long lasting items, it can be hard to do that unless you can afford a personal tailor and no gifts to deal with.
It's a complicated topic. Clothes and linens are more cheaply made, even when you look hard, even in my lifetime. I'd argue people often don't even know what something well made in a category looks like often anymore, which distorts demand and therefore supply.
