The nation’s leading political fact-checker has debunked Hillary Clinton’s recent attacks on Bernie Sanders’ healthcare plan.According to Politifact’s recent analysis of Bernie Sanders’ proposal to expand Medicare to all Americans under his “Medicare for All” single-payer healthcare system, Sanders’ plan would save the average household between $505 and $1,823 per year — just shy of a $1,200 average cost savings. While this figure is lower than the Sanders campaign’s estimate of $3,855 to $5,173 in savings, it still means American families will pay less under single-payer healthcare than they currently do under the Affordable Care Act.Sanders’ plan is modeled after single-payer legislation he introduced in 2013, which outlines how the plan would be implemented and paid for on a nationwide scale. First, Sanders would impose a 6.7 percent payroll tax on employers, along with a 2.2 percent healthcare tax on those making less than $250,000 per year. Sanders includes higher percentages for incomes above $250,000 in his legislation (the richest 2 percent of the U.S. population) and a 5.4 percent surcharge on the wealthiest Americans whose modified adjusted gross income is above $1,000,000 (literally less than 1 percent of Americans). Sanders’ bill also includes a 0.02 percent financial transactions tax on Wall Street trading.
