Republicans are going to have a hard time winning national elections in the future as long as people believe they care about only the “rich and powerful.” American Enterprise Institute president Arthur Brooks makes that point this week in a Wall Street Journal column.

Conservatives are fighting a losing battle of moral arithmetic. They hand an argument with virtually 100% public support—care for the vulnerable—to progressives, and focus instead on materialistic concerns and minority moral viewpoints.

The irony is maddening. America’s poor people have been saddled with generations of disastrous progressive policy results, from welfare-induced dependency to failing schools that continue to trap millions of children.

Meanwhile, the record of free enterprise in improving the lives of the poor both here and abroad is spectacular. According to Columbia University economist Xavier Sala-i-Martin, the percentage of people in the world living on a dollar a day or less—a traditional poverty measure—has fallen by 80% since 1970. This is the greatest antipoverty achievement in world history. That achievement is not the result of philanthropy or foreign aid. It occurred because billions of souls have been able to pull themselves out of poverty thanks to global free trade, property rights, the rule of law and entrepreneurship.

The left talks a big game about helping the bottom half, but its policies are gradually ruining the economy, which will have catastrophic results once the safety net is no longer affordable. Labyrinthine regulations, punitive taxation and wage distortions destroy the ability to create private-sector jobs. Opportunities for Americans on the bottom to better their station in life are being erased.

Some say the solution for conservatives is either to redouble the attacks on big government per se, or give up and try to build a better welfare state. Neither path is correct. Raging against government debt and tax rates that most Americans don’t pay gets conservatives nowhere, and it will always be an exercise in futility to compete with liberals on government spending and transfers.

Instead, the answer is to make improving the lives of vulnerable people the primary focus of authentically conservative policies.
