I agree for most things, they were just built to last a lot longer because product quality was a priority. These days, a company doesn't want you to buy once, they want to sell you a product that lasts just long enough you'll buy the same brand after it breaks. I'm a tradesmen and I can attest, the older a tool is, usually the higher quality it is. Same goes for lots of equipment. I once saw a sears model pressure tank from 1972 still in working condition when newer tanks last 5-10 years and the average before that was 15-20. That specific case might be survivorship bias, but every retiree i talk to will claim sears had some high quality stuff when they were yoinger.
