The best part about the system is that it uses big corp’s Hollywood accounting against them.
Oh, per your US tax return, we see that you earned 0.4% profit on your US sales last year. You’d be fine with a 1% royalty after we sell it for half price, right?
If the US began importing high quantities of drugs from Canada, what prevents Pharma companies from insisting that Canada pay current US prices?
If Canada declines, the companies could stop selling in Canada.
I would think in many cases the profit from selling in Canada at all is less than what they'd lose from allowing them to be imported to the US.
