“Their plan to repeal the I.R.A. and double down on the Trump tax cuts for the wealthy will worsen inflation,” said Jared Bernstein, a member of Mr. Biden’s Council of Economic Advisers. “On top of that, they’re also explicit that they’re coming for Social Security and Medicare, making this a terribly destructive agenda that starts by fighting the Fed and moves on to devastating vulnerable seniors.”
Conservative economists say the inflation impact of extending Mr. Trump’s tax cuts could be much smaller, because those extensions could lead businesses to invest more, people to work more and growth to increase across the economy. They also say Republicans could help relieve price pressures by following through on their proposals to reduce federal regulations governing new energy development.
“Those things are going to be positive for investment, job creation and capacity” in the economy, said Donald Schneider, a former chief economist for Republicans on the Ways and Means Committee and the deputy head of U.S. policy at Piper Sandler.
A budget proposal unveiled this year by the Republican Study Committee, a conservative policy group within the House Republican conference, included plans to permanently extend the Trump tax cuts and to impose work requirements on federal benefits programs, in hopes of reducing federal spending on the programs and increasing the number of workers in the economy.
“We know for a fact that federal spending continues to keep inflation high, which is why a top priority in next year’s Republican majority will be to root out waste, fraud and abuse of taxpayer money,” Representative Kevin Hern, Republican of Oklahoma, said in a statement. Mr. Hern, who helped devise the budget, called it “one of many proposals to address the dire situation we’re in.”
As they eye the majority, top Republicans have suggested that they will consider an economically risky strategy to potentially force Mr. Biden to agree to spending cuts, including for safety-net programs. Representative Kevin McCarthy of California, who is the minority leader and is seen as the clear pick to be speaker should Republicans win control of the House, suggested to Punchbowl News this month that he would be open to withholding Republican votes to raise the federal borrowing limit unless Mr. Biden and Democrats agreed to policy changes that curb spending.
How to use that leverage has divided Republicans. Some, like Representative Nancy Mace of South Carolina, who fended off a Trump-backed primary challenger, are supportive of that option.
