A lot of companies that make things have two separate lines: consumer and enterprise. Consumer is for us poors that the company doesn't need to respect. You can buy more expensive, higher tier consumer items but it's just as fragile. You're paying for more bells and whistles. Enterprise grade is stuff that will actually last because it is often sold in a lot as part of a contract and the contract won't be renewed if the items suck. These things are often just not sold to consumers because why would you ever buy consumer-grade garbage if you could buy this?
For something like computers, this looks like how pricey "gAmiNG" laptops look all fancy but fall apart in about the same timeframe as the lower end laptops for students. But if you've ever handled the sort of laptops for banks or businesses, you'd wonder why laptops can't all be like this. People swear by Lenovo Thinkpads for a reason. Dell's Latitude (general productivity) and Precision (has the power of a gaming laptop but far less bs) lines, HP's probooks, all feel really nice and last for-fucking-ever. But you can't buy them in a store even if you wanted one.
So the trick is to buy what big organizations are buying, but you likely gotta get 'em secondhand when the orgs are done with them. For basic clothes, mil surplus might be a good port of call, for technology see an e-waste recycler or sometimes government auction (you just gotta know what to ask for; ThinkPads, Dell Latitude/Precision, HP Probook/Zbook). Otherwise try to thrift old, pre-enshitification items. The blanket I had as a kid is still going strong and has lived to bury multiple sets of newer bedding (which have worn thin and torn). Kitchen items, see if you can shop at a restaurant supplier.
TL;DR: if you need an item, think "which business needs these to function" and see where they 1) buy theirs (suppliers) or 2) sell their old ones (surplus) and buy that. If you can't do that, look at older, pre-enshitification things.
