The idea that "everyone should buy their own house at 22 and sign on for a 30 year mortgage" is a horrific scheme concocted by federal and corporate bureaucrats hell bent on building a compliant worker class. And it has effectively fallen apart: if Bloomberg Businessweek readers (do they exist? I've never met someone who reads it) want millenials to start making substantial financial commitments, the best they could do would be to, yeah, create some actual jobs for people.
And, sure, there's the alternative of renting. Which is fine if someone wants to do it--in fact, I got out of my parents' house ASAP after spending a year of menial labor to save up enough to start on my own. But people living with their parents is hardly some absurdity or perversion. In fact, it's a pattern that's observed cross-culturally and has occurred throughout history. Probably most people throughout history have lived with parents, up to and including during marriage. Today people still do as well.
If anything, it's the idea that everybody needs to have their own house and their own car and their own backyard that's the perverse one.
