The first few lines of the article are misleading. They talk about young people going to college, but then talk about all young people living at home. Not all young people go to college. So this has directed the line of thinking to be purely about college grads.
I personally have friends who never go to college, or even drop out of high school, live at home, completely unemployed, not seeking work, because their parents abide by it. Stressfully, but they abide it.
Or they take the minimum wage job, buy big tvs, smart phones, booze and pot, and live like they are in college in their parents basement.
Then I know some who have graduated but didn't choose the right education and are no more employable than my bum friends, like having a History degree. So they take minimum wage jobs, and though they are motivated people, they have huge debt to pay down, so opt to live at home.
For others the $200 "parent" rent is a huge incentive. I am personally going to be taking advantage of this deal when I graduate and am gainfully employed, which luckily I know now that I will be.
The real factor at play here is one with several consequences, and that is the piece about the Baby Boomers. First, they are only now starting to begin retiring, opening up the job market to younger people. Secondly, they were raised in a nuclear family environment and so have done the same. Dad works, Mom stays home, and they have two or three kids. That's more kids than jobs. As a final topper to that, now that the kids are old enough that they don't need their bums wiped for them any more, Mom wants to go to work, and is taking some jobs up.
The real problem comes in another 15 to 20 years, when those Boomers need their own bums wiped. We think it's awful kids are moving back in with their parents now. Soon enough it will be our parents moving back in with us. Just wait.
