Well, there's one country I'm not moving to. It amuzes me that a first world country, hell, a global superpower, doesn't have any of that stuff, it would benefit everyone, especially free healthcare because you wouldn't have to worry about going bankrupt just to get that surgery you know you need. It doesn't even have to be free, just making it affordable for everyone is already a huge step.
The first/second/third world designation is a cold war relic. America is first world by definition, but we probably should have ditched the whole framework after the Berlin Wall fell.
I agree that it should no longer be used in a modern context. It's like calling Russia the USSR; people usually know what you mean, but it doesn't make sense, and when talking about specifically American geopolitics, it's easy to misunderstand what is meant if you are older than 35.
Yet it still considers itself a global superpower with the biggest economy in the world (or one of the biggest, I can't even remember). To me, it's just laughable that they made it to this point.
