President Donald Trump, who campaigned on a promise not to cut Social Security, is reportedly considering a plan to eliminate much of the payroll tax that funds the critical safety net program.According to the Associated Press on Monday, the proposal is being floated as the Trump administration goes \u0022back to the drawing board in a search for Republican consensus behind legislation to overhaul the U.S. tax system.\u0022The AP reported that one option \u0022circulating this past week would change the House Republican plan to eliminate much of the payroll tax and cut corporate tax rates. This would require a new dedicated funding source for Social Security.\u0022And that, Zaid Jilani wrote at The Intercept, \u0022would require counting on Trump\u0026#039;s economic team to shepherd a solution through Congress—and for Congress to treat Social Security unlike other \u0026#039;discretionary\u0026#039; general-fund programs whose budgets rise and fall with political currents.\u0022The AP continued:The change, proposed by a GOP lobbyist with close ties to the Trump administration, would transform [Texas Republican Rep. Kevin] Brady\u0026#039;s plan on imports into something closer to a value-added tax by also eliminating the deduction of labor expenses. This would bring it in line with WTO rules and generate an additional $12 trillion over 10 years, according to budget estimates. Those additional revenues could then enable the end of the 12.4 percent payroll tax, split evenly between employers and employees, that funds Social Security, while keeping the health insurance payroll tax in place.This approach would give a worker earning $60,000 a year an additional $3,720 in take-home pay, a possible win that lawmakers could highlight back in their districts even though it would involve changing the funding mechanism for Social Security, according to the lobbyist, who asked for anonymity to discuss the proposal without disrupting early negotiations.Although some billed this as a bipartisan solution, and President Barack Obama did temporarily cut the payroll tax after the Great Recession, others note it probably would run into firm opposition from Democrats who are loathe to be seen as undermining Social Security.\u0022Furthermore,\u0022 Jilani noted, \u0022the rumored mechanism for making up the lost funding...would hit workers the hardest.\u0022A value-added tax \u0022would increase the cost of goods and services,\u0022 Jilani explained, citing Paul N. Van de Water, a senior fellow at the left-leaning Center for Budget and Policy Priorities, \u0022arguably canceling out the value of the reduced payroll tax for most lower- and middle-class workers.\u0022In a column on Monday, Michael Hiltzik of the Los Angeles Times described the plan as \u0022an absolutely terrible idea, partially because it smells like a back-door way of cutting Social Security benefits. It needs to be nipped in the bud.\u0022Indeed, Nancy Altman, president of the advocacy group Social Security Works, called the scheme \u0022a Trojan horse: It appears to be a gift, in the form of middle class tax relief, but would, if enacted, lead to the destruction of working Americans\u0026#039; fundamental economic security.\u0022She wrote on Tuesday:If Trump proposes this Trojan horse, it would be the newest shot in the ongoing Republican war against Social Security. That war has failed so far. The American people overwhelmingly support Social Security because they appreciate that it provides working families with basic economic security when wages are lost as the result of death, disability, or old age. And it does so extremely efficiently, securely, fairly, and universally.Having suffered defeat on their frontal attacks against Social Security, Trump and his Republican allies in Congress appear to be contemplating a stealth attack, instead. In the 1980s, Republicans, who had long tried but failed to cut government programs directly, discovered a new tactic. They realized that they could undermine government and eventually force cuts to spending by cutting taxes and, in their words, starve the beast. Now, Trump is making plans to use that same tactic against Social Security.Of course, it\u0026#039;s probably not Trump himself that\u0026#039;s behind the proposal, but members of his cabinet who have been targeting safety net programs for years.\u0022Does Trump understand that Social Security is funded through payroll taxes?\u0022 wondered\u0026nbsp;Daily Kos senior political writer Joan McCarter. \u0022Does he even care? Nah. That\u0026#039;s the detail stuff that he has people to understand. Those people, however, are undermining his promises. And if they actually try to go through with this? He might become the first president in history to have single-digit approval ratings.\u0022Meanwhile, a proposal to expand and fortify Social Security was re-introduced in the U.S. House last week—with more co-sponsors than any such legislation has had before.
