The U.S. unmarried birth rate leaped up to 40% recently, from less than half that in 1980. This keeps pace with large rises in unmarried births in European countries.
In Europe, though, the state gives money and services to couples. In the U.S., many more of those unwed mothers are married to Uncle Sam.
We need marriage more than Europeans do. If we have the same percentage of kids of unmarrieds that they do, our kids will be worse off.
