Read about this here and here. From the former:
Consider, for example, the proliferation of for-profit schools, hospitals, and prisons, and the outsourcing of war to private military contractors. (In Iraq and Afghanistan, private contractors have actually outnumbered U.S. military troops.) Consider the eclipse of public police forces by private security firms—especially in the U.S. and the U.K., where the number of private guards is almost twice the number of public police officers.
Or consider the pharmaceutical companies’ aggressive marketing of prescription drugs directly to consumers, a practice now prevalent in the U.S. but prohibited in most other countries. (If you’ve ever seen the television commercials on the evening news, you could be forgiven for thinking that the greatest health crisis in the world is not malaria or river blindness or sleeping sickness but an epidemic of erectile dysfunction.)
Medicynical Note: Some would say that our dalliance with “market” based health care has led us to and/or exacerbated our cost/quality/access issues.
