It makes all the sense in the world to live with your parents if both parties have agreed upon what the child will contribute to the deal. I'm sure most parents would probably like to include some sort of exit strategy (to use an oft. used phrase these days) in that plan. I think the article was dealing more with otherwise well-educated, mature 20-somethings with indecision regarding what route life should take, causing or contributing to financial dependence, keeping them living off of the parents out of necessity, not by choice.
If I were living in the same state as my parents and making what I do now, I'd probably be living with them and finding some way to contribute to house hold chores, utilities, carrying my weight, etc.
How old is the guy when he starts being undateable because he lives with his parents?
