China is pretty crazy and jails people for talking about Winnie the Pooh.

Complete BS. Here's an exhibit on "The Many Adventures of Winnie the Pooh" in Shanghai Disneyland. It’s absurd that this is the only nonsense you can muster to justify China’s higher life expectancy (even given semi-colonial subjugation).

Cuba and Vietnam also have lower life expectancy than the US.

Cuba is a tiny country that has been massively sanctioned by the largest imperialist nation on earth (the US) for 60 years (after they defeated the U.S.-backed dictator Batista and stopped being a sugar colony of America). It seems that according to the World Bank (super unbiased lmao, and yes this is the same organization sourced in your Wiki article), Cuba's life expectancy is ~73 while the U.S. is ~76. Personally, given the huge gap in development compared to the two countries, and that Cuba has not engaged in imperialism once whilst the U.S. is known for such things, this small difference is relatively impressive for Cuba and makes you look like a brainworm-infested child for implying a level playing field.

I didn’t think I’d have to explain Vietnam’s history of colonial subjugation by the French and imperialist plunder by the French, U.S., and U.K., of which millions of Vietnamese were killed through bombing/being burned alive. History does not matter of course, so let us analyze their life expectancy: ~74 years, whereas the U.S. life expectancy is ~76. With all this in mind, a two year gap somehow justifies the inherent “superiority” of the U.S. system!

Look at Hong Kong

I’ve looked, and @Awoo@hexbear.net already gave an excellent response to this (which of course you ignore in your reply). Don't act snarky unless you've earned it, and you haven't earned it.
