The cost of the US health system can be blamed on the ABA as much if not
more than the AMA.
They're both in the same racket along with the drug and insurance companies.
I did a google search and here is a good article on how the free
market has been trampled so effectively by the AMA. Its also
interesting to see that even some of the founding fathers of the US
saw this coming:
"One of the signers of our Declaration of Independence was the
physician and psychiatrist Benjamin Rush, MD. He was also involved in
writing our Constitution. He warned, "unless we put medical freedom
into the Constitution, the time will come when medicine will organize
into an undercover dictatorship to restrict the art of healing to one
class of men and deny equal privileges to others; the Constitution of
the Republic should make a special privilege for medical freedom as
well as religious freedom."
