It's interesting; the effects of the availability heuristic are insidious. Of course, I thought about local effects in the States. But seeing this a day later, it dawned on me that such a drug could prove a bigger boon for Africa than a cure for AIDS, and perhaps likewise in much of the second and third world.

I'm not saying any particular scope is "correct," but it's interesting that the discussion here deals almost entirely with the welfare effects on the immediate job market, and ignores the very likely substantial effects on distant peoples.
