Ritical Thinking about universal healthcare. (in the USA)

In this essay I need something like a logical argument for OR against universal healthcare.(health for everyone) in USA. I am not saying how this will be paid for or that you will need to support or be against the current Obama plan, which is not technically Universal healthcare. Please keep in mind the type of plan we are talking about is a program in which everyone would get the same healthcare, regardless of their ability to pay. this is what I (you) need to argue for OR against. CAN you please use critical thinking removing all kind of emotional bias. Please remember not emotional matter at all, dont feel bad for those who will be paying for those who cant. thanks.
