When men and women fail to form stable marriages, the first result is a vast expansion of government attempts to cope with the terrible social needs that result. There is scarcely a dollar that the state and federal government spends on social programs that is not driven, in large part, by family fragmentation: crime, poverty, drug abuse, teen pregnancy, school failure, mental and physical health problems.
