"I pay no more in tax for my health coverage than any average middle-class American. The co-pay is less than $100 annually. So why can't more Americans have that?"

You have a job that offers it and that is great. I pay 100% of all my employees health care. But take another 10% in taxes from your employers and soon there is not money to do that anymore. Health care benefits might only cost you $100 but your employer paid through the nose(unless you work for the government then someone elses employer paid) Keep raising taxes and there will be no jobs or health care coverage because employees and health care are the two biggest expenses and will go first in cutbacks.

I'll say this once again. Our health care package where I work is negociated as part of a total wage package. Nothing is "given" to us, we defer wages into the health care package.
