You've picked on the worst-off countries in western Europe, but tell me about the best-off like Germany or Scandinavian countries. As far as I can tell, they have pretty generous social welfare schemes but are pretty sound economically. How does that factor into your model? Could it be that other cultural factors are at play?
I think that may be a hint that he's blaming the wrong things: it's pretty strange to blame the U.S.'s social-welfare system for the country's disparities, when the U.S.'s social-welfare system is so stingy. Social Security is not why the older generation has so much more money, because it's pretty impossible to get rich off a social-security check in the first place (I know elderly who live off social security, and…

This is thus leading to entirely odd outcomes as there is a mis-match of earnings/liabilities for personal balance sheets for teh yound. ie, moving jobs/et vs massive debt it takes to run housefold/pay for future kids school, etc.
Its also an equity problem for texes. one or two good years get taxed and two or three lean years later, you lost a bit chunk of earnings to takes. if you had smooth earnings, you would pay lower taxs, etc. whereas the older generation is sitting on tax-free capital gain on housing, so low income/low taxed, yet they are conrolling massive asset value.
