I see it this way:
-People aren't perfect. We are often ignorant, stupid, cruel, selfish, etc. At the same time we are often knowledgable, kind, giving, etc.
We are human.
Parents being human too.
-Many people do not know themselves nor live 'in' themselves. Many have deep old needs (neurosis etc if you like) which prevent them from living authentically.
This, in turn, distorts the human vision of the world. It 'causes' all sorts of shenanigans.
Those who can not see themselves, can not see others - how to love unconditionally in this sickly state of being?
This is the way it has always been. This is the way it will continue to be. Different images and textures; but the same old crap.
You grow up - and you just might get a chance to look at this world on your own terms.
That is, after screwing up tonnes along the way, and painful self examination. Continual. If you choose - or not.
Crap hand or not: it is up to each person to decide whether or not/how much of the load they want to take for themselves.
Self responsibility.
In my opinion, some get an easier time of it than others by the roll of the die (certain circumstances, certain influential people, etc etc).
No matter.
It's all part of the deal. You get your one life and that's it.
There is this rather strange series of books i read called Diamond Heart. A.H. Almaas describes most people as babies looking at each other as potential Tits. I loved that. "How small is it? How much milk does it have for me? Will it be sweet or sour?"
I'm sorry if I ranted off topic or being boring. I have considered this too.
I think it's part of growing up and into oneself...or at least trying to.
Part of it, to me it seems, is finding a way to let it be. To accept it, not blame or try to force change where it's silly (Like in the Matrix: some are not ready to be unplugged and so must be dealt with as essentially dangerous ina way).
And ya do what you can. I'd gander that it goes on and on: if/when I have kids, they'll 'rebel' against the rules too...trying to understand for themselves. And probably have a lot of anger and blame for me.
