... Why do you think this is going to be special to the US?
Do you think other cultures don't have consumerism? (they do). Or maybe other countries have old stuff more often?
I like cheap, used furniture. But I also understand that furniture wears out. I've had legs break, arms split, cushions lose comfort. Beds get lumpy. Finishes wear off. Drawers come apart and dovetail joints break. Some of it becomes unreliable or unsuited for daily use. Fine, keep your linens in that old dresser, but using it daily will hasten its end - that one drawer is barely together, after all.
Not to mention that some of these things are just not usable in modern society. An old desk might be pretty, but it wasn't designed with a computer in mind. Good luck fitting your great-grandmother's dining room table in your small dining room. It was made for 8, and you have a family of three. Beds with a metal boxspring built into the frame aren't as comfortable to sleep on as you might imagine and can be quite squeaky. Some old furniture just won't fit in your abode either - and boy, oh boy is some of it absolutely filthy.
Sometimes you can fix this stuff, if you have the time and space and equipment to do so. Many folks don't.
And of course lots of folks replace cars. In most places in the US, you can't survive without a vehicle. A vehicle that breaks down is a vehicle that can get you fired. It is much easier to keep up with an older car if you don't have to rely on it. And again, you still have issues with having to be able to have the time, space, and tools to work on it - and you might need to have enough strength.
And so on.
