“Under the market system, there is demand for a product if a lot of people want it - but that demand counts for nothing if those people have no money. If they lack money, their demand essentially doesn't exist…This explains why the drug industry is not investing money to develop a cure for a disease known as sleeping sickness, which leaves its victims in a coma. The disease…killed 66,000 people last year and threatens to infect 60 million more - but the only people who are afflicted by it are poverty-stricken Africans with no clout in the marketplace. Interestingly, there is a drug called eflornithine that is effective in lifting victims out of their comas. But drug companies stopped producing eflornithine in 1995 because it was no longer profitable to continue. The drug was still desperately needed, but only by people without money. So, following modern market practices, these people were simply left in a coma.”
