For all the shit everybody gives Boomers, I'm pretty sure the majority of them are also poor and working class. There's just a lot more wealth at the top, or the "top" is bigger.
I think it's more about the stereotypical Boomer attitude than their wealth. The whole "I worked hard at the gas station and saved up and bought my house in 1974 for $20,000, so I don't see why all of you younger people are having such a hard time" thing.
Like I said, stereotypical, but it transcends economic status.
Even many poor, working class people of that age own their homes after all.
