I'm not sure if that's what he meant. I think what he meant is that: use poor people cheaply for testing ==> make drugs faster ==> more poor people saved I'm really interested in the ethical questions involved in this matter, I'm sure of what side I am ethically on this, because I simply have to imagine what it would be if _I_ was the poor guinea pig (which could have happened btw, I was really really lucky to born to middle-class parents). But this is on very slippery slope; when you become desperate, it's where you start trying to justify a class of human beings as being `lesser'; and once you do that you've opened Pandora's box (Aryan race etc etc)
