Isn't much of rebellion simply an attempt to bring some form of order into our lives... correct wrongs, end oppressive unnecessarily restrictive actions, to be free of insanity, etc?
The reason for the majority just "settling down", "growing up", "getting on", etc, is that their rebellion lacked real focus as attention was always outward; directed at the glaring injustice, the false morality, etc.
If we focus outward we'll end up disillusioned with our impotency against that which outnumbers, and can so easily over power us. We'll grow weary with lack of progress, with being caught in endless contradiction, with the willingness of the masses simply to submit, etc.
So what to do? Surely the only answer is, understand the real problem.
Sure society is shaped so that only a few can actually live life freely while everyone else labours in an existence of servile functionality. Sure the social structures aren't at all sociable, and every institution should be institutionalized. However, maybe that is just the wrong direction in which to focus, perhaps the only way is for ourselves to be free.
I'd say it's blatantly obvious that running around downing every drug in sight, drinking every pint of whatever, being sexually irresponsible, having millions upon millions is not freedom as all return varying degrees of pain rather than pleasure... accidents, addictions, attachments, conflicts, diseases, psychotic problems, etc, etc, etc.
Most do not understand what freedom is. Hence, our society fears freedom most. But let's go into this, what is freedom?
