Trump's recent foray into Iran has indeed hit fuel/gas prices, the supply chain of some regional goods, and will have a knock-on impact on other goods subsequently due to rising fuel costs. The impact of tariffs on consumers is largely confined to the US.

I was mostly trying to make the point that the cost of living crisis is global, affecting many countries, and that your US-centric view doesn't scale. Healthcare costs hitting consumers directly isn't global as most countries have totally different systems.

That said, your suggestion that the answer to rampant capitalism making healthcare unaffordable is more rampant capitalism (which you call competition) is... interesting.

And I wasn't advocating for Sanders personally or his policies specifically, just using him as an example of a conviction politician who might have had the chutzpah to take on and dismantle the business-lobbying-politics establishment.
