i agree wholeheartedly, but the next comment by boona ("Considering it costs between $100 million to $1 billion to get a drug approved by the FDA (depending on the study you look at), I can see why they wouldn't touch it.") highlights the issue: profit is only an incentive to do it; the initial cost is there either way and somebody has to cover it. if it's not private companies, who would that be...?
