And not only that - buying trash today when you know that you'll be moving soon and possibly have a better income next time you buy. We are putting off major purchases because we can - because there is that option, and the user value of of 'trash' is 80% of that of the version that costs 10 times as much.

Also, at least in the home electronics space, there is a good chance that the 'trash' in 3 years time will be better than the quality product today (in short term functionality if not in longevity).

12 years ago I bought the best quality TV I could afford. And while it still works perfectly, it's objectively worse in just about every way then a current TV costing 20% of what I paid for it. However since it was so expensive and still works I cannot really bring myself to replace it.
