Another media oddity

If Rush Limbaugh is right that socialized health care will ruin our medical system, then why is medical tourism one of the fastest growing areas of tourism? Why are people finding it to be cheaper to fly to another continent, pay for a hotel, pay for the entire cost of the procedure, and then fly home then to get the procedure done in the states? It's thought that 750,000 Americans went to other countries in 2007 and about 1.5 million in 2008 for health care reasons. If we have the best health care system, why did so many Americans find it necessary to go to countries with nationalized healthcare in order to get treated? Why are the same procedures much cheaper in those countries?

in summary
American Health Care insurance cost (price you pay after insurance coverage) >> round trip plane ticket overseas + hotel + total price of procedure + follow up visits (either there or in the states since these aren't always covered by your insurance if the procedure was done some where else.)
