Does everyone make a good parent?

It has been assumed that everyone makes good parents. Just as, some people make good engineers and some will not, some make good lawyers and some will not, some make good doctors and some will not, yet it has been taken that everyone makes good parents. Such is definitely not the case. Who then will pay for the upbringing of children abandoned by their parents? The State could pay for the upbringing of these children and when they grow up and find jobs, these children will pay back to the State through additional tax. This will give an opportunity for children who have been abused, neglected or abandoned to fully develop their potential. Another way could be to set up a children’s fund and the sponsors be given shares from this fund and when the children grow up and find jobs, they contribute back to the fund.
