A foundational value in our nation is the opportunity for all its citizens to be able to compete for a fair and meaningful shot at the American dream. This begins with access to citizenship, educational opportunity, and securing meaningful work that leads to greater life opportunities via commitment, diligence, and self-sacrifice. But an important contributor to putting and keeping men, women, and children on the escalator toward the American dream is little-known and widely ignored. Just 70 years ago, social mobility and protection from poverty were largely a factor of employment. Those who had full-time work of any kind were seldom poor. Fifty years ago, education marked the gulf separating the haves from the have-nots. For the last 20 years or more, though, marital status has increasingly become the central factor in whether our neighbors and their children rise above, remain, or descend into poverty. The research is astounding. Charles Murray of the American Enterprise Institute explains in his important book “Coming Apart: The State of White America” that in 1960, the poorly and moderately educated were only 10 percent less likely to be married than the college educated, with both numbers quite high: 84 and 94 respectively. That parity largely held until the late 1970s. Today, these two groups are separated by a 35 percent margin and the gap continues to expand. All the movement is on one side. Marriage is sinking dramatically among lower- and middle-class Americans, down to a minority of 48 percent today. No indicators hint at any slowing. It’s remained generally constant among the well-to-do. This stark trend line led Murray to lament, “Marriage has become the fault line dividing America’s classes.” He has company in this conclusion.
