One big family...but are they happy about it?

Thank God for parents and grandparents -- where would we financially-strapped kids be without them? And more of us are moving back in with them, Amy Hoak reports at MarketWatch.com.

So dust out the attic and turn that office back into a bedroom, Mom and Dad! But it's not only "boomerang" kids returning to the nest, says Hoak. Some older Americans who lost their retirement savings are moving in with family, too.

According to an AARP Bulletin survey, 11% of people ages 35-44 said they live with their parents, and 11% of people age 50 or older said they live with their grandchildren or parents. That means more American households have three generations under one roof.
