THE WALL STREET JOURNAL: Huntsman’s Good Economic Plan: Better than anything so far from the GOP Presidential field.

The heart of the plan lowers all tax rates on individuals and businesses. Mr. Huntsman would create three personal income tax rates—8%, 14% and 23%—and pay for this in a “revenue-neutral” way by eliminating “all deductions and credits.” This tracks with the proposals of the bipartisan Bowles-Simpson commission and others for a flatter, more efficient tax system.

That means economically inefficient tax carve outs for mortgage interest, municipal bonds, child credits and green energy subsidies would at last be closed. The double tax on capital gains and dividends would be expunged as would the Alternative Minimum Tax. The corporate tax rate falls to 25% from 35%, and American businesses would be taxed on a territorial system to encourage firms to return capital parked in overseas operations.

Mr. Huntsman would repeal two of President Obama’s most economically debilitating creations, ObamaCare and the Dodd-Frank financial regulation law. Mr. Huntsman has it right when he says, “Dodd-Frank perpetuates ‘too big to fail’ by codifying a regime that incentivizes firms to become too big to fail.” He’d also repeal a Bush-era regulatory mistake, the Sarbanes-Oxley accounting rules, which have added millions of dollars of costs to businesses with little positive effect.

Mr. Huntsman says he’d also bring to heel the hyper-regulators at the Environmental Protection Agency, Food and Drug Administration and the National Labor Relations Board, all of which are suppressing job-creation.

Not bad.
