* Your comparison between Portugal's social security system and the US's includes only one source of support, but several are available. (Cost of housing is one.) Neglecting this easily-verifiable fact has the same misinformational outcome as lying.
* "Medicaid has extremely low out-of-pocket costs" is not a reply to "we didn't pay a fucking cent". Your (not-included) estimates of how much money a US resident definitely will have to pay is by definition never going to be as good as zero. It's almost like you're setting out to smooth over this also-easily-verifiable fact with "rhetoric".
