Is Korea a third world country?
No. If by Korea you mean South Korea (since 'Korea' normally
means the South, NOT the North; North Korea is a separate country
and it's always referred to as 'North Korea'), the answer is an
incredulous "Are you kidding?". Korea is one of the richest
countries in Asia, with a very high standard of living. It's also
one of the largest economies in the world, despite its small size.
It boasts a very high-tech popular culture, with way faster
internet than pretty much any other country, east or west. It's one
of the world's leaders in robotics and consumer electronics today,
as well as exporting a huge amount of popular entertainment
products such as movies and TV programs all over the world. It's
rich, advanced and progressive. Immigrants from other countries
flock to Korea in search of a better life. North Korea could be
referred to as being a third world country due to its
under-development and poverty.
