Can you clarify your thought here? American people don't think and behave like they do in Hollywood TV shows. There are exceptions of course, but most pop TV shows do not attempt to accurately portray real human relationships, emotions, actions etc.
Do you mean to say that there is something particularly American about Squid Game? When I, an American, watched it my biggest thought was that it seemed very much like an anime. Especially some of the early scenes like the chase by the loan sharks or the paper game played in the subway. It felt distinctly not like normal American television in that regard, though of course you can't create TV in 2020 without having some influence by Hollywood.
