I haven't seen that poster but I have seen others on various platforms portray Europe as Utopian and the rest of the world as an unlivable hellscape. Even their political class cannot help themselves: https://www.euronews.com/my-europe/2022/10/19/josep-borrell-apologises-for-controversial-garden-vs-jungle-metaphor-but-stands-his-ground
Despite Europe's centuries long parasitic relationship with the rest of humanity they still think that they are the good guys while everyone else is the problem.
Isn't that their default mode?
