According to your third link, the household wealth of the bottom 40% grew by 157% between 1989 and 2001, and the middle 20% had their wealth grow by 200%.

The majority of your links focused solely on relative measures, not absolute ones (i.e., the incomes of the poor grew more slowly than the rich).

Want to try again?

Would you consider YOURSELF middle class if you only had access to what a '50's middle class family had? A 1920's one?

Hmm, ok, I'll choose my own arbitrary definition of middle class - it involves flying cars, robots and spaceships. No one meets my definition in the present era. In contrast, 20 years ago, when I defined "middle class" as stone knives and bear skins, everyone in the US was middle class.

Oh no, we are all so poor, something must be done!
