Barack Obama called during his State of the Union for taxpayer-funded universal preschool for children, which would yank them out of their homes at an even earlier age.

But a new study shows the opposite – family cohesion, is the No. 1 determinant of a healthy home and a healthy society.

When asked about the message from the study, which showed only 45 percent of 15-17-year-old teens in America live with both married parents, Lt. Gen. William G. Boykin said such cohesion is as important in the home as it is on the battlefield.

“Family intactness, when measured, always has a beneficial influence on U.S. social policy outcomes,” said Boykin, who serves as Family Research Council‘s executive vice president.

Boykin, who commanded all the Army’s Green Berets, notes that whether a family stays together or not is the greatest predictor of teen pregnancy, school performance, income and reliance on the government.
