Here's a good example of rationing in a universalized system:
Canada is able to buy prescription drugs at a discount from the USA ONLY because the pharamaceutical companies figure they can afford to sell LIMITED amounts of prescription drugs to Canada (and other poorer countries) by separating markets and cost-shifting higher prices to Americans who are willing to pay more for their prescriptions in the form of health insurance premiums. This is wonderful for Canadians, right? (but not for us, because we pay the higher prices to compensate...)
Canadian pharmacies figured out that they can profit from their discounted prices by selling their drugs back to Americans in the free market at a premium, through illegal reimportation. This is good for Americans. But who ends up with the short end of the stick?....
Canadians are now experiencing SHORTAGES of certain prescription drugs such as Lipitor, and Canadian pharmacies are now LIMITING patients to 30 day supplies in order to compensate. RATIONING. Ultimately, it is the ONLY solution for universalized systems. They can't make up for the shortages with production from their own pharmaceutical firms, because the technology just isn't there. Their socialized system has stifled development of prescription drugs in their own country. Thus, they have to depend on the USA for their supplies of prescription drugs.
Is this how we want America to end up? Think about it. Because, if we universalize and force price controls on our pharmaceutical companies, it will work for a while, but in the LONGRUN....Americans will begin see shortages of prescription drugs, just like the Canadians are now beginning to face.
