Organized medicine, more specifically, the American Medical
Association, played a key role in the repeal of the popular
Sheppard-Towner Act in 1927. The Act was ratified over the
objections of the AMA in 1921, who thought the legislation
constituted "socialized medicine." The act was "a federal program
prividing mathching funds to the states for the establishement of
prenatal and child health centers," and was very successful. The
Act was very popular in its time, so its demise was almost solely
the work of the AMA and their very powerful lobbying apparatus. See
