Until John D Rockefeller the oil tycoon came along, mankind was kept healthy with natural cures to disease. But Rockefeller bought off the medical establishment to promote his petroleum based prescription drugs. The centuries old natural cures were branded primitive and medical schools began teaching form new textbooks, funded by Rockefeller, of course, that promoted mew "miracle drugs" that Rockefeller happened to own patents for. Anyone who protested was labeled a kook by the MSM, also owned by Rockefeller, and in a few short decades, he held a monopoly on the healthcare industry.
