It wasn't an example. Instead of answering, you moved goalposts and asked "why don't you import stuff from Canada".

However you look at your "example", it's not good for the US.

- Canada has universal healthcare

- Canada has government regulations

- Despite all that, insulin in Canada costs less than in the US

So the original question still remains and is valid: why is insulin in the States so damn expensive? Given that the US is one of the largest insulin manufacturers in the world. And it's produced by literally the same companies.

Because the government grants the insulin manufacturer a monopoly over its citizens and enforces it with the law.

The same monopoly exists everywhere because there are very few insulin manufacturers in the world.

Try again.
