How Can Republicans Respond To Inequality?

Josh Barro believes that the GOP should support certain forms of redistribution:

The dirty secret about the last 30 years' rise in pre-tax income inequality is that we probably can't reverse it. Instead, we will have to rely on policies that ameliorate it on an after-tax basis — that is, the dreaded redistribution of income, or "spreading the wealth around."

Some redistributive policies are more economically damaging than others. If conservatives made peace with the need for more redistributive economic policy, they could fight to make sure it is pro-growth. For example, they could focus on minimizing poverty traps created by means-tested entitlements, and making sure the tax base is broad so progressivity can be achieved with relatively low tax rates.

Roughly, this is what right-of-center political parties in Europe do.
