Some of what I said for 16 yo applies as well to many of their parents. The US school system, at least, no longer teaches civics. Many school systems refuse to keep score during sporting events and give a trophy to all participants so nobody FEELS slighted!
Many of those 18 year olds get in serious trouble with those contracts as well. They almost never read them, believe what the sales agent tells them. Many kids are facing bankruptcy when they clear college. Not from student loans, although some of the companies involved in that business are little better than loan sharks!
