The exploration of class separation may be more subtext in The Host than it was text in Memories of Murder, but it still provides fertile ground for exploring the absurdity of authorities that perpetuate the separation of people. Also, go see Parasite!
The authorities weren’t after the family because they were “other”, but because they happened to have been in the path of the monster. And a quarantine is the perfectly sensible reaction to an actual epidemic, the government just happened to be wrong about that being the case. I take it as a satire of the incompetence of the South Korean and U.S governments, not as an argument that no government should have that kind of authority.
