It is not. Saying so, reduces the intrusiveness and carelessness of the american system and absolute insanity of the chinese scoring system.
The SCHUFA is a problematic institution for sure, but saying it's equivalent to the chinese scoring system just shows that you don't know what you are talking about.
Because they state that free healthcare is automatically bad healthcare. Which, as a general statement, is just wrong.
Free Healthcare is a broad term for dozens of different policies in dozens of different countries. Just because OP's specific country has problems, doesn't mean that every single implementation of free healthcare leads to bad healthcare. Also a similar rhetoric is used as a dog whistle by the far right in the USA.
Additionally they are using a specific question about their situation, to rant about a much broader topic. This soapboxing called behaviour is generally frowned upon.
So the comment in isolation is wrong, attention seeking & looks like written by someone who is something between a manchild, that is unable/unwilling to present a nuanced opinion, and a nazi. All of which are imho criteria for a downvote.
Yeah you can do that. You would be wrong and people around you would wonder why you switched the subject. But you can do that.
