That’s sort of what it appears right? Teaching what moral code means and decision making should be parenting 101.
No, I have not failed any children. I am not a parent.
You have a lot of control over your children's development, but don't think for one second that if you provide zero financial support that they would never become a prostitute based on moral and decision making tutelage, alone.
Decision making doesn't necessarily lead someone away from prostitution. The wage is incredibly lucrative, compared to taking a menial job. It actually makes a lot of sense for those who can get over it. A smart person is smart enough to realise that there is nothing immoral about selling their services for sexual encounters, too. Who is being hurt? Nobody. It's a transaction and it isn't unethical or immoral. It's pretty seedy and horrible to be associated with, yes - but it isn't a question of ethics or morals.
I realise that you would never be able to accept this, of course - most parent's egos are so huge about the job they are doing, the only way they realise that they do not wield absolute power over the child is for them to experience the child exposing them to a rebuttal. To me, just saying "bad parenting" when you're talking about a decision to bypass the wage structure is naive. I wouldn't say that about many aspects of parenthood but I would say it about something that is so obviously rewarding.
And yes, I do know someone who exploited this situation and no, I did not use her services. She's a lawyer now

She was in a city, alone - without a job and could work 10 times the amount so she could live - or she could do that.
