I think it will be tangential in its development. First the Federal government will require all physicians to become members of the “Federal Association of Physicians”. Then they will enact a law requiring, ‘in order to practice medicine all physicians will be required to join the “Federal Association of Physicians”. Then they will enact a law which requires in order to practice medicine, all members of the “Federal Association of Physicians” must not discriminate against any patient and is required to conform to the requirement that they treat any and all patients as prescribed by the act and agrees to comply , upon penalty of fine, and or imprisonment, to treat any patient coming to see him. If he refuses he forfeits membership in the”Federal Association of Physicians”, and thus cannot practice medicine on any patients in the states or territories of the United States of America.
