I don’t think you really understand the meaning of “strawmans” (or basic statistics for that matter), but you have otherwise completely missed the point and it’s not really worth arguing over.

Not so much denying statistics as saying that they are extremely misrepresentative of what life is like in Cuba, and it’s clear that anyone who thinks otherwise has never actually been there. It’s not really a competition about who is living a better life in abject poverty, but if it were you certainly would likely prefer to be in any of the poorer capitalist countries you mention. I appreciate any recommendations for reading material though, I’ll check it out. Since you seem to be impressionable, here’s some light reading for you: https://academic.oup.com/heapol/article/33/6/755/5035051

I can’t tell if this is a joke or not. First try actually going to Cuba, then venture a bit outside whatever city you flew into (e.g. cienfuegos, trinidad). Hilarious to see people on the internet quote statistics like this (that are at best misrepresentative but more likely straight up inaccurate) and who have absolutely no idea what the reality of life is like there. Or maybe try talking to someone who came from there. I would imagine North Korea is comparable on all the measures you listed. I feel sort of bad that you’ve been duped by some propaganda piece that you read online, but unfortunately you won’t be the first or the last.
