Why does society make it so hard for you to turn your life around?

Say you were involved in criminal activites, or were addicted to substances or even just failing out of school or work for some amount of time in the past. Then suppose you did your time, went to rehab, learnt skills or whatever to get somewhere in life, no matter what you do, society still will always look at you like a lost cause.

They will always ask why you did not adhere to the life script strictly, why you didn't go to the best school, why you don't have good jobs, why you don't make money. That will always matter and the unique circumstances of your life that pushed you into hard times don't.

We all know how hard it is for ex-convicts to find gainful employment, employers have serious prejudice against ex-addicts or people with no proper work history. Its like people love to preach about redemption, and second chances, and all that bullshit but in reality they think you deserve to suffer and not have anything in life just for a single screwup in your past, regardless of how hard you've tried since to change yourself.

Everyone, EVERYONE, is out only for themselves, and themselves alone. Adult relationships are ALL transactional. If there's nothing you can do for others you aren't worth their time. Which, I mean I understand all that, its only natural, but then why do they have to pretend like they are better than that? At least have the spine to accept your true nature ya wimps.

No wonder so many people fall back into the same destructive patterns all over again. When everyone gives up on you and you're systemically barred from improving yourself, there's no way to cope with feeling that helpless in life.
