<p>When I was 18, the age of majority was 21. I lived in an all-girls’ dorm with a curfew, and if I had gotten into trouble at school, my parents would have been called. That may have been an excess of supervision by today’s standards, but it was not so much that students failed to grow up and become independant adults. I don’t think that 18 year olds themselves are any more mature now than they were then.</p>
