President Ronald Reagan with economic adviser David Stockman

Reagan budget adviser David Stockman has today’s must-read op-ed, labeling the Paul Ryan budget plan an “empty conservative sermon:” Paul Ryan’s Fairy-Tale Budget Plan.

The Ryan Plan boils down to a fetish for cutting the top marginal income-tax rate for “job creators” — i.e. the superwealthy — to 25 percent and paying for it with an as-yet-undisclosed plan to broaden the tax base. Of the $1 trillion in so-called tax expenditures that the plan would attack, the vast majority would come from slashing popular tax breaks for employer-provided health insurance, mortgage interest, 401(k) accounts, state and local taxes, charitable giving and the like, not to mention low rates on capital gains and dividends. The crony capitalists of K Street already own more than enough Republican votes to stop that train before it leaves the station.

In short, Mr. Ryan’s plan is devoid of credible math or hard policy choices. And it couldn’t pass even if Republicans were to take the presidency and both houses of Congress. Mr. Romney and Mr. Ryan have no plan to take on Wall Street, the Fed, the military-industrial complex, social insurance or the nation’s fiscal calamity and no plan to revive capitalist prosperity — just empty sermons.
