If you assumed the skewing of medicine toward the drug-addicted model that poses for conventional medicine has only been around a relatively short time, it's been alive and well for ages, according to writer and biographer Eustace Mullins, whose 1988 book, Murder by Injection, is the gist of this short Google video.
Mullins argues medicine's propensity toward needless drugs and procedures began long ago, as the Rockefeller Syndicate, U.S. government officials and the American Medical Association formed an unholy triumvirate that successfully gained control of America's health care industry in the early part of 20th century.
Although the book has been long out-of-print, I strongly urge you to read this chapter about the syndicate (especially near the bottom of the link) that demonstrates how far this group has gone to hold onto its monopoly of medicine in America.
