Of course many Americans would like Universal Health Care. Problem is they want it for "free". Or, at least they want it at someone else's expense. The truly poor can get free healthcare, esp women & children. Free to them at least. Someone has to pay for it in the end. And of course, that's the citizens who are working and paying taxes. About 50% of Americans pay NO income tax but many still receive a "refund" via the Earned Income Credit.
Most of us (who do pay taxes) think our taxes are high enough already. For example -- If my employer pays a $10,000 bonus for Christmas (or end of year bonus) to me, the cost to the company is $10,765 (plus some other minor taxes based on that amount). After federal, state, local and social security taxes are withheld from my bonus, I will receive about $6,000 total (or only about 55% of what it cost my employer).
At what point am I paying enough in taxes to provide benefits to others (many of whom pay NO taxes)? Plus, for the 40+ years I worked, I paid all or part of my health insurance cost of premiums, plus still had to pay a deductible and co-pay (usually 10%). Now that I'm over 65 yo, I qualify for the federally provided Medicare health insurance (which covers elderly & disabled). But I still am required to pay some costs out-of-pocket. Last year that amount was $4000. Plus, often we must appeal to get procedures that the insurance company originally denies.
There ain't no free lunch.
