Taxes required would completely halt the economy.

Proudly titled "Medicare-for-All," the Sanders scheme would eliminate the private insurance industry and establish a single, federally run insurance pool open to all.

Sanders promises a healthcare utopia – a future of "no more co-pays, no more deductibles and no more fighting with insurance companies." During Sunday's debate, the candidate claimed that his health care plan would "save the average middle-class family thousands of dollars a year."

This is complete nonsense. Every other single-payer system around the world delivers subpar care at astronomical cost. Worse still, the multitrillion-dollar tax hikes – that's "trillion," with a "t" – that Sanders has proposed to finance his single-payer monstrosity would decimate the American economy.

Voters in need of a definitive reason to dismiss Vermont's "democratic socialist" as a legitimate candidate now have one.

Sanders's "Medicare-for-All" proposal would require $14 trillion in new public spending over the next decade and would expand the size of the federal government by over 50 percent. He plans to cover those costs by ratcheting up taxes on virtually everyone. He wants to hike income tax rates by 2.2 percentage points and levy a new 6.2 percent payroll tax on employers. He'd also dramatically crank up income tax rates for families making over $250,000 year. And he'd set the estate tax at 65 percent.

These new taxes would slow our economy to a halt. They'd rob businesses of capital to invest in expansion and job creation. The returns on entrepreneurship would dwindle. Corporations would direct investments to friendlier environs abroad.
