ANOTHER SHAME

From Dennis on Facebook:

From my lecture this afternoon: Of all of the nations in the Organization for Economic Cooperation and Development (OECD) only three (the US, Mexico and Turkey) lack universal health care. Every other developed nation in the world has it. And Mexico and Turkey are both in the process of implementing universal care. In four years America will be the ONLY country in the developed world without universal care.

Why can't the US, the richest country in the world, implement universal health care?
