A very simple problem arises when people attack Obama's health care proposals. If you are afraid "the government might have death panels," "the government might make you wait weeks for care" etc. etc., you then have to show why this either doesn't happen or won't happen if we keep the current system, with insurance companies in control of funding health care.
We know that insurance companies do exclude people because of pre-existing conditions, they do revoke coverage if you get sick, and they do put lifetime caps on the care that they will fund. We also know that they have to pay huge CEO salaries that dwarf even the President's annual paycheck. So if you are going to argue against Obama's plan, just please tell me what you are afraid the government will do and why you think you don't have to worry about United Health or whoever your private insusre is doing the same darn thing.
I'm not saying that there aren't any arguments that can be made against Obama's plan. What I am saying is that you can't make these arguments without comparing what you are objecting to with present reality.
