You can still buy a 1950s-style toaster that will have a 1950s-style toaster function and lifetime.
It's just that $22 in 1950s dollars is $320 in 2022 dollars. Each 2022 dollar is worth nearly seven cents in 1950.
I believe you can still get 1950s fridges as well, it's just that you're looking at around $6000.
Almost all these "productivity" improvement have in fact been cutting corners. Wheat costs 11 pence a bushel, and a real toaster still costs $22. The price of money has changed, so this is less obvious than it should be.
