Your numbers of fatherless are numbing. So staggering are they both pachyderm and pack animal should blow and bellow. But they don’t because in their constant tug-of-war for dominance over a declining culture the dust they kick up obscures the truth that you are saying because fatherhood is dying.
For all time it is true: fathers are indispensable to the health of nations because fathers are indispensable to the health of families.
Theodore Roosevelt said over a century ago that
the tasks connected with the home are the fundamental tasks of humanity. When home ties are loosened; when men and women cease to regard a worthy family life, with all its duties fully performed, and all its responsibilities lived up to, as the best life worth living; then evil days for the [nation] are at hand.
