"Thirty is the New Twenty"?

Many movies have based their entire plot on making a joke about a male who refuses to grow up. In Van Wilder, he refuses to graduate and move on into the real world. Similarly, in Stepbrothers, the two 'kids' are actually over 30 year old men who refuse to move out and get a real job. Although we watch these movies only to get a good life, they pose a good point about our society, also brought up by Kimmel in Guyland: our society is entering adulthood later and later. Staying in school longer is necessary to get a good degree, but now that getting a job is harder to do, a lot of time it's required to move back in with the parents. In this website they discuss how to set rules with your adult living in the house. They talk about how to keep rules and basically how to deal with a child who just wont grow up. If you google 'adults living at home' there are thousands of other sites like this one. Obviously, Kimmel must be correct if this many parents are looking for help with their adults.
