Being older doesn't completely help really. Yes we are old enough to have an income, but we still have to get the income. Also, once you get to that age (I'm 19) you don't really have a reason to do anything that were against your parents rules much. It's true that I stay out all night some times(rave, party go out with friends to their places or mine, camp just about anything), but never more than twice a week, and normally not more than once a month. Other old rules fit, a human body doesn't very well hold up to finding extra time or fun. Work takes up enough time and energy that you really don't need the extra stress on your bodies. Most of my friends are Bronies so that is a huge amount of our time spent anyway, music art watching or even just talking. Also work takes more than school ever did....
Also, I don't even have kids, which take more time and energy.
So really there is a draw, you have no money, but it is the time of your life where you have the time.
