For many Steve Jobs is just a name or a good American film. For some, he was a genius of the technology company, creator of devices like Ipad and Iphone. For a few, a patient with a rare pancreatic tumor that luckily in his case could be removed. For almost anyone, he was a man of science who lost his life paradoxically by preferring naturopathic treatments without scientific basis.

Perhaps this is the most publicized case, but every year in the world lives are lost to the seductive set of theories, covered in a mystical tradition or technological advanced, which are offered as an alternative to traditional medical practice.

But, what to do in a market that sets a single price for a product, whatever its quality, or in the face of a high-income earner who can afford the product at any price? With this marketing initiative producers win, because they receive the necessary stimulus to continue contributing from the...
