Is it normal to believe that you don't owe society anything?
I didn't ask to be born. As long as I choose to do what I like and not hurt anyone else it's fine. But I don't owe society anything. No one does. Being a good person is one thing (That's more of a moral obligation though) but other then that, you aren't obligated to live the live society constructed for you:
1) Go to school. Including college. Get a job.
2) Get married soon after college. Move to a child-friendly suburb.
3) Have the 2 kids.
and
4) Work until you're 65 and retire.
You're not a loser if you decide to spend time doing hobbies you like. No time is wasted if you use it to your liking. Besides, I have SSI that mom uses to pay the rent (along with my brother's SSI). I can afford to not have a job for a little while. With how the American economy is, it's not likely I'd be able to find one anyway. And I refuse to work minimum wage at a fastfood joint or retail.
