Poll: Since the education standard has gone up should we raise the adult age?

Apparently we chose 18 as our magic number because that is when people graduate high school. Since a having a high school diploma doesn't mean anything in this economy and 36% of homeless people are under 25 shouldn't we give high school grads a few more years of childhood before their parents can legally kick them out?

In my opinion we should and while we are at it lets add a few years to high school so they can earn the basic college credits you get with a 2 year in liberal arts I knew kids who got some free credits in high school so its not impossible. Two birds( Having to pay for gen ed in college when you should of been taught that stuff in high school/making people smarter) one stone (extending high school and childhood).
