US GDP is much higher than most (all?) European nations.

And as you accurately pointed out, US population is also higher, and have different costs of living. Which is why we compare countries in % of GDP and not in raw dollars spent nationwide, which would make no sense at all.

The US also has a massive population, which means a much larger insurance pool, which means the risk is spread out over a much larger swathe of people (and ethnicities, lifestyles, etc.).

Doesn’t make any difference when you go over a few million people (or possibly much less)

So I’m not going to say this pic is accurate, as I have no actual numbers on this

Well I do, and this pic is clearly bullshit.

Just because you like the message doesn’t mean you aren’t allowed to point out obvious lies.
