I think it's an excuse.  I mean, I know rents are often high, but a lot of times it takes some elbow grease.  Anyway, the situation of being with parents - as in a couple - seems to always lead to social problems.

Just think about it.  If the couple could produce an income (as in having enough elbow grease for at least one to work), they wouldn't be there, but if they can't produce an income, they're going to want to work for the parent - but that's often a sticky situation.  Imagine a couple being with an elderly person and the accusations from other family members.
