whether you pay for it in taxes or pay cash to your doctor you end up paying regardless
why is taxation so unpalatable 
I'm going to assume you are asking for a serious answer.
Most of this clusterfuck is the direct result of democrat incompetence and politics as usual. You'll never have affordable universal health insurance without tort reform, which Al Gore cast the deciding vote against.
1% of Americans already pay 39% of taxes. This (health care) is not a tax problem.
I'll go a step further and argue that there aren't ten programs the Govt. efficiently runs. Nationalizing healthcare without having an infrastructure (that works efficiently and pays in a timely manner) will only lead to waste. No one can afford to keep their office open while waiting for Medicare/Medicaid to reimburse without private insurance and co-pays. Unless people are surgeons, do a lot of DME or pain management procedures .... Medicare/Medicaid office visits are essentially charity unless doctors overbook.
IMO, the only way to successfully nationalize healthcare is: return it the community level, Tort reform and debt management. Have doctors obligated to x amount (E.g. 10) hours/week at community centers in exchange for repayment of their student loans with the cases malpractice covered by the govt.
The doctors shouldn't be compensated in any other manner because the Govt is incapable of paying actual claims on time. The Govt
can manage a monthly electronic payment or check for a fixed amount. They should be free to work private insurance or fee for service elsewhere.
People who believe nationalizing healthcare is simply a matter of further taxing the rich do not understand that delivering healthcare has real costs. Only someone either already rich or seriously capitalized could possibly afford to run any business based upon the Govt's payment system. Overhead (insurances, rent, utilities, worker's Comp., salaries, 401k, paper, computers, billing, etc..) eats up 50-65% of the typical office's cashflow. That's the logic behind my argument that it must be returned to the community level.
It's more a case of ignorance than stupidity. People really believe all doctors are rich and that their co-pay goes to buy jewelery, McDonalds for their kids or a car payment. People also believe every dime paid by their insurance company is profit. Only about $41 of a $100 bill ends up being pre-tax income.
