The data says that living standards for the middle class has risen, not fallen nor stagnated as you claim.
You can manipulate the data to say that the sky is made of grape jelly.
I'm going by real facts. I'm also going by what I see in my own life, my family's lives, and people I know lives...
We are not doing nearly as well as our parents did even with more education.
And yet my husband and I have done considerably better than did our parents. And our children have done considerably better than we have. I am observing the same trends among our friends, family, neighbors. So my anecdotal experience trumps yours if that is the criteria to be used.
Maybe if you got out of the union hall and saw how the real world works without artificial manipulation, you might have a different perspective.
