I challenge anyone to show that throughout the history of the world, that medical doctors (healers) were commonly of the wealth castes the likes of lawyers and merchants, and perhaps kings?  It seems that the rise of Western healers was as of late, perhaps since the 19th century upon the heels of scientific discovery of vaccines making possible centralized hospitals and clinics.  This in turn, thrust pharmaceuticals into the dog-eat-dog marketplace ruled by merchants.  Throughout history, including the time of Jesus Christ, healers were more assuredly poor and reliant upon the charity of society...by their choice.  They hardly expected a Mercedes chariot, palatial Kahala residence, royal influence, or even plumber's wages.  That is, not until they rebranded as Western healers.  Now, we get crocodile tears from western doctors victimized because their income is no longer guaranteed by insurance.  Even plumbers don't have that guarantee.
