Oh the noble Americans! Suffering under the yolk of oppressive pharma so the rest of the world can take advantage! Praise be.
Really, though, it's absurd to demand that the rest of world be grateful. Try changing the system in the US and you will find it exceedingly difficult due to the deep pockets of big pharma and the massive role money plays in the US democratic system. So no, the rest of the world should not be grateful that a capitalist system is doing what it does.
