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 they live at a subsistence level). The well-off older people with huge retirement accounts got them from the private sector and the stock market.
What's changed is that the '60s-'90s economic/employment situation is probably not going to repeat itself. My dad had basically a guaranteed-for-life job once he got a college degree, and a generous defined-benefit corporate pension, neither of which really exist anymore. And if you didn't go that route, you could apprentice in a skilled trade and also have a good middle-class job.
