how does someone know that if a couple is fucked up, their children would be fucked up too when they grow up?
Maybe most of them grow up to become thieves, scammers, addicts, gamblers, criminals or anything at all, but we could not say for certain that if someone is too much fucked up in life, their children would be like that too.
And on the contrary, if a couple is perfect, does that guarantees that their children would not do something wrong in their life?
I believe that the biggest scammers in the history had the most educated parents.
A number of terrorists had educated parents.
The more rich parents are, the more their children would have money to get spoiled in life.
The more messed up the life of parents are, the more they would want their children's life to be better than themselves.
Consider anyone, does they want their children to be better than themself or worse?
So I kind of don't agree to your point about this thing.
