Yes, you have to ask how many people don't realize their critiquing has an unconscious jealousy behind it. I used to be a student bum and lived in a van which prompted a guy from a house in the street to come out and berate me, at first he said I was scaring his kids but we kept talking because he seemed to want mostly to reconcile in his mind how I lived like this. He had several "but don't you.. but don't you want". To my "No, no no, I'm just happy... " Eventually I admitted something along the lines of "But I'VE had to work so hard [to get the things that I require for happiness]" (it's not fair)
There certainly is something enviable in someone who can be completely happy, content, and satisfied as a bum living in a van. But I don't think the average young adult man living at home is doing so because they have reached Enlightenment.
