All this guy says is that the companies adjust prices to demand in such a way as to maximize profit. That's what I told you. I'm not saying it isn't true, I'm saying it isn't right. The only reason drugs cost more here is because we can afford to pay more, or at least, those who can afford them at all are numerous enough. This is not acceptable.
In commodities required for human life, like food or drugs, the price should be determined by the cost of production of the commodity, plus a reasonable profit for the producer. Rationing by cost is fine for electronics and sporting goods, but no one should go hungry or sick because the seller wants to charge him more than another guy across the border simply because it maximizes his return.
