Mr. Ryan’s sonorous campaign rhetoric about shrinking Big Government and giving tax cuts to 'job creators' (read: the top 2 percent) will do nothing to reverse the nation’s economic decline and arrest its fiscal collapse,” Stockman wrote in the op-ed, later adding: “Mr. Ryan’s plan is devoid of credible math or hard policy choices.”

Stockman, who resigned in 1985 in protest over deficit spending, has added his voice to a chorus of economists criticizing Ryan’s "Path to Prosperity," which would give tax cuts to the wealthy while slashing funding for programs like Medicaid, Medicare and food stamps, all in the name of reducing the national debt.
