Canada produces drugs at the same cost we do, they just have price controls, we'd get the same buy implementing those ourselves and not create a massive trade deficit. However, price controls are a weird bug where intellectual property and future R&D makes up most of the cost. If I spend a billion dollars on something that costs $1 to make but expect to only sell 100,000,000 of them, I must charge $11 a pill to break even. If I have another available market, say a country willing to buy 10,000,000, but they have a price cap of $6, it is still logical for me to sell to them at $6, if everyone suddenly buys from there instead though, I will only make $550,000,000 in revenue, or a loss of $555,000,000 instead of the profit of 1.1 bil plus 60 mill minus 1.110 bil, or $50,000,000 I would otherwise have made. Different can of worms then when production is mostly price of labor and materials, and that itself is a monstrous issue where import/export is concerned.
