I dunno. I guess the doctors figured it was okay to do so. What you did not see in the headlines was all the people going bankrupt due to high health care and drug costs. That is considered the norm in the U.S. under the current system.
I know a young hardworking fellow 28? without job health insurance who got cancer and was told the treatment would cost him over $200,000. Luckily he was Canadian and got on the first bus to Toronto for excellent treatment that cost him about $150 in hospital costs! I kid you not!
