President Obama would like us all to believe that there are only two choices on healthcare: his plan and the current situation. In fact, he beats this straw man up whenever possible. His position is that if you are against his plan, then you must be in support of the current system. This is incorrect. One can, in fact, be against Obama's plan and the current plan.
One argument made by conservatives and libertarians against universal health coverage is that governments are incapable of controlling costs. This is incorrect. Before we dive into that, however, let's work through a couple of definitions. When discussing health care, many people (especially pundits and politicians) refer to "cost" when they mean "spend". "Cost" refers to price at an individual level, whether for a person or a procedure. "Spend" is an aggregate amount of the costs of all the procedures for a population.
