Conservatives need to stop denying reality. The stagnation of the incomes of middle-class Americans is a fact. And only by acknowledging facts can we respond effectively to the genuine difficulties of voters in the middle. We keep offering them cuts in their federal personal income taxes — even though two-thirds of Americans pay more in payroll taxes than in income taxes, and even though a majority of Americans now describe their federal income tax burden as reasonable.

Meanwhile, the argument over same-sex marriage has become worse than a distraction from the challenge of developing policies to ensure that as many children as possible grow up with both a father and a mother in the home. Over the past 30 years, governments have effectively worked to change attitudes about smoking, seat-belt use and teenage pregnancy.

And so we arrive at a weird situation in which the party that identifies itself with markets, with business and with technology cannot win the votes of those who have prospered most from markets, from business and from technology. Republicans have been badly hurt in upper America by the collapse of their onetime reputation for integrity and competence. Upper Americans live in a world in which things work. The packages arrive overnight. The car doors clink seamlessly shut. The prevailing Republican view — “of course government always fails, what do you expect it to do?” — is not what this slice of America expects to hear from the people asking to be entrusted with the government.

Equality in itself never can be or should be a conservative goal. But inequality taken to extremes can overwhelm conservative ideals of self-reliance, limited government and national unity. It can delegitimize commerce and business and invite destructive protectionism and overregulation. Inequality, in short, is a conservative issue too. We must develop a positive agenda that integrates the right kind of egalitarianism with our conservative principles of liberty.
