Who stops you from buying insulin outside the US and re-selling it in the domestic market?
Fascinating that drugs in Canada are perceived as so much cheaper than in the US, and yet, you know that Canada doesn't have a socialized prescription drug program? Instead, provincial health programs negotiate drug prices. You know who can't do that? Individuals. Also, Medicare.
The medicare example is quite an interesting one as well. The US doesn't have the political momentum to let medicare negotiate pharma prices, and before such a basic thing is even changed, you want to hand over the entire health care insurance industry to the government?
