The whole "Caucasian" theory really fell apart, so really no one is "Caucasian", but lets pretend that it is reasonable for arguments sake.
Finland, Malta, Israel, Estonia, and Hungary would not be "Caucasian". None speak Indo-European languages. Hungary is not quite a First World nation, but I would say Estonia is. Their First World history is only 30 years old, but it has been a good 30 years, and they are about as well off as Italy. Hungary has a similar number of years, but those years have not been as good.
A Nazi racial "scientist" would guess the Sami/Finland slanted eyes are East Asian, but the genetics are actually held on a completely different part of the DNA. They are superficially similar, but are genetically different.
Finland and Estonia have the best education scores in the world. Hungary has the highest rate of geniuses in Europe. Israel... Well we all know the stereotype about Jews being brilliant. Malta... Malta... Malta is the exception that proves the rule that non-Caucasians are just smarter than Caucasians.
Being in the First World seems to have more to do with what region a country is than its genetics. For instance, East Germany became part of the First World, because the Iron Curtain came down, not because their genetics changed. If anything, West Germany had more immigrants from other parts of the world.
Many months ago, I wrote an incomplete list, that was incomplete. Wow, you caught me being right and saying it was an incomplete list.
So why is Israel and Malta, with their Middle East genetics able to be first world nations? Why are Finland and Estonia, with their Central Asian genetics able to be first world nations?
