Huh? Korea was one of the poorest countries in the world in the 1950s, they’d just experienced a full 40 years of brutal racial oppression, colonialism, and war. And by your metric, North Vietnam during the 60s should have been an economic powerhouse. But their GDP per capita in 1964 was less than half of Chad or Sudan’s.
And since you’re complaining about people not knowing their history you might want to brush up on where the terms “first world,” “second world,” and “third world” came from and what they actually mean. Who knew that terms invented in the 1950s to specifically describe the geopolitical alignment of countries during the Cold War are applicable to the late Middle Ages?
