Such a lazy argument, Moe. Just tired and lazy. Other countries have markedly different economic and societal structures, but yeah since they have it we should. Love how all these countries that we get compared to are 0% like us *and* have the freedom to have zero military because they live under the blanket of our protection. I bet if we told everyone to eff off, US military is out of here, we'd have a few more pesos floating around for whatever dumbass spending you want.
Not to mention the radical gap between our current system and what they have will absolutely shock people if implemented. Have there been any countries similar to the US switch from a system like ours to single payer successfully? Nope. We are clearly unique. There is no template for what you want, you want Panacea and it is unattainable.
