So Bernie Sanders' plan considers healthcare as:
Bernie’s plan will cover the entire continuum of health care, from inpatient to outpatient care; preventive to emergency care; primary care to specialty care, including long-term and palliative care; vision, hearing and oral health care; mental health and substance abuse services; as well as prescription medications, medical equipment, supplies, diagnostics and treatments.
And the main way to raise revenue to pay for it will be:
A 6.2 percent income-based health care premium paid by employers. A 2.2 percent income-based premium paid by households. Increasing Progressive income tax rates on certain brackets. Changing qualifications for capital gains, dividends, and deductions. Increasing the estate tax on certain brackets.
Now I am assuming the cost the healthcare products and services will fluctuate just like all other products and services do in one way or another. My question is, under such a plan, in a given year, what happens when the costs of the products and services is less than revenue (do taxpayers get the difference back) and what happens when the costs of the products and services is more than revenue (will taxpayers see an increase to percentages taxed of their income).
