Yes, chriopractors are quacks, but so are most "medical associations," in particular the most powerful groups who have the government pull, and whose primary concern is influencing regulators to exclude competition from the market. While the public perceives them as bastions of legitimacy, medical boards are great evils in society, are themselves the very thing they claim to be "protecting" us from. There is no scientific evidence that government medical bodies protect the health of individuals. The notion that it does is actually the archaic one. In antiquity, and the medieval times, there was strict government control of science medicine. There were things that only certain people were allowed to do. The average person was not to think, only to have faith in authority. The Enlightenment, with gave birth to science, was a period of gradual DE-REGULATION of medicine, finally reaching its culmination in the early period of the United States, when medicine was virtually an unregulated fee market. The standard of care advanced more rapidly during that period than at any other time, before or since. Today medicine is stagnant because one again, it is government-dominated. yes, chiropractic is quackery, but so is the whole product of American government-run medicine. America is NOT a "for profit, free market" heathcare system , it is an ANTI-COMPETITIVE, government owned one.
