The health care tax could be regressive, say 5-10% of your income below first $100-150k, and then 0% of the remainder. This way, even the richest would not be affected that much by that additional tax.
Actually, even without additional tax, if US government dropped Medicare, Medicaid and other state sponsored insurance systems in favor of universal coverage, it would have enough money to have world-class healthcare system without any additional taxes -- the US government _already_ spends as much on health care per capita as Germany, or France, and 30% more than UK.
