Republicans get huffy when you call their plan a voucher scheme, but that’s exactly what it is

Medicare is a government-run insurance system that directly pays health-care providers. Vouchercare would cut checks to insurance companies instead. Specifically, the program would pay a fixed amount toward private health insurance — higher for the poor, lower for the rich, but not varying at all with the actual level of premiums. If you couldn’t afford a policy adequate for your needs, even with the voucher, that would be your problem.
