I grew up in a small town near Chicago. We had a small black population. All of them lived in single family homes. They had a mother and father. The father worked and the mother stayed home with the children. They never got into trouble and most of them went on to college. And there was no welfare. How did this happen? The intact family, that,s what, and education.
I heard Charles Murray on a show a while ago promoting a new book. In the book, Murray tried hard to look, not at skin color, but at income and marriage rates. His conclusion was that we don't have a problem of inequity in this country. We have a "marriage gap". Those who were married and stayed married, no matter what their skin color, did a lot better than those who did not marry.
Marriage is important. For many reasons. This is why the left is so intent on destroying it.
