The conservative hesitancy to put the issue of poverty at the center of our domestic economic agenda, rather than tax rates or middle-class jobs, is misguided — politically as well as substantively. Any analysis of the so-called War on Poverty, officially at the half-century mark this year, will find that the numbers are very strongly on the side of the conservative critique of the welfare state: We spend a great deal of money, achieve very little in the way of measurable positive good, and inflict a great deal of destruction on families and communities in the process. Addressing poverty in a meaningful and robust way calls for a response from every part of the conservative coalition, because we have a generation’s worth of social-science research documenting that poverty is only partially an economic phenomenon. Poverty is complexly intertwined with marriage and family, with childbearing habits, and with the prevailing norms in local communities. The cause-and-effect relationships here can be complicated, and they operate at the community level as well as the individual level: For example, poor children with married parents experience better long-term economic outcomes than do those with single parents, but the more significant variable, according to a fascinating Harvard study on the subject, is the prevalence of marriage in their communities. It matters whether a poor child has married parents, that is, but it matters even more how many of his friends and classmates have married parents. The free market is part of the solution here, but it is only a part of the solution. But whether the question is the organization of our families, the organization of our tax code, or the organization of our schools, conservatives are well-positioned to step in and do something about the mess the Left has made of things, if only conservative leaders — and, especially, Republican elected officials — were more inclined to do so.
