You are missing the point. Baby boomers inherited much of their wealth from their parents, as will their children. Your graph is true of every generation. But thanks to improving health care, the average life expectancy of people has been extended so they are passing on their wealth later and the younger generation are older when they inherit it.
Baby boomers are between 58 and 76 years old. Looking at your graph, that means around 55% of the national wealth will get redistributed to the younger generations. Looking at their saving patterns, do you think they will know what to do with so much money? Is that the real threat to our economy, when "the now" generation gets cash that should be earmarked for investing, but chooses to spend it instead?
Meanwhile, at the younger end, the average time someone spends in school is getting longer as more and more people pursue more education. I think that trend is finally starting to moderate as people are learning a degree does not automatically confer wealth. What you learn is more important than how much time you spending learning.
I do think people are fleeing northern urban America with its high crime rates and high taxes and high cost of living. But they are not leaving America, they are just moving to where progressive liberal policies have not yet destroyed the quality of life in the name of an ideology that sounds better on paper than in practice.
But don't despair, even the progressives of San Francisco have begun to see the light. The recent recall election marks a turning point. But it is good to see that even you have begun to acknowledge that if America continues on its move to the left, it will collapse. For now there are places in America to flee to that have not bought into progressive ideology and things there are doing quite well.
