If your society is set up so that health care needs are the basis of for-profit corporate business plans it will end badly.

The constant refrain these days, when Facebook and Google+ are brought up is, "if you aren't paying then you aren't the customer you are the product." The businesses are actually farming - offering tantalising free social tools and games to fertilise their realms to attract millions who arrive with valuable data about their shopping habits and personal details ready to be scraped.

In similar fashion, drug corporations along with other 'health care' businesses are farming the physical state of citizens of that aforementioned society. A quick cure is not a profitable cure, and a rare malady is unlikely to receive any attention. Best case scenario for the businesses is, like that for parasites in general, a host rendered chronically ill but neither cured nor killed.
