I'm a young Boomer / Old Gen Xer, and to me things are pretty good right now. Jobs are available, 401k balances are good, etc. My own kids are in college or headed to college, and the same is true for most of my friends (across the economic spectrum).
I read about how disastrous things seem to this author, but I haven't seen it. My business travels have taken me to both coasts and I live in the middle, I don't see the widespread misery described. I see opportunity for all stripes of people being offered and taken.
To be sure, I do think life will be tougher for our kids. The same economic opportunities I had have changed, but there seem to be new ones springing up.
I think it's just life going on. Good luck to next generations....
