Your mentality is typical of people from low-trust societies - "lol those naive Westerners" (lokhi[0] in Russian). But while individuals in high-trust societies can indeed be lokhi, everyone in a low-trust society is, collectively. They are giving up on the social development and institutions that only work well when trust in people you don't know is a societal value. They are defective at best, and nonexistent at worst, in a society where everyone treats each other with scepticism, disdain and distrust by default, until proven otherwise.

Thing is, it's not the case. The world outside of a narrow circle of rich, white, Protestant countries has never been like this, and those countries too, are losing it because of changing racial composition, and immigration from low-trust cultures. And in a global world, high-trust groups are simply being taken advantage of.
