There's no doubt about it: if you go to college, graduate, and then move back home with mommy and daddy, you are a loser

Why? My parents made time for me. My father worked 60 hours a week when I was growing up and he still took me fishing trapping and hunting. Now I'm graduated worked 8 years at a multinational invested in income properties and I'm effectively retired at 29. Now my mother doesn't have to cook nearly as much (I do) and my retired father has some one to fish, hunt and trap with, his retired son. I haven't move back in yet but live nearby and am considering it.

These articles generally imply, if they don't specifically state, that the "adult children" are not contributing meaningfully to the parents' household work or expenses.
That's very different from the situation you and some others have described, of generations sharing a household with everyone benefitting.
