It's probably safe to say that parochial schools are more selective than public schools when it comes to students. However, not every child's family is that fortunate. However, these children are fortunate that public schools embrace them with open arms. To these children whose lives seem hopeless, public schools offer hope. To these children who may lack proper ethical values, public schools can teach them ethics.
People can criticize public schools all they want.
I have heard your arguments before. However, I am one Catholic who will not hesitate to get down on his knees tonight and thank God for public schools. To these children who lack guidance, public school teachers can give them direction. To these children whose lives seem meaningless and full of despair, public school teachers can teach them a better way of life. After all, someone has to teach these children.
