Hate to burst your bubble,but “third world” doesn’t have to do with wealth, or lack of it. During the cold war some pundit stated that the countries of the world were in three camps, the free world, which are the US and the West,the Communist world and the non-aligned countries or third world.
True, that’s how the meaning started, but the typical understanding of the term “3rd world” has meant impoverished S Hole for a long time.
I guess I could have said “developing countries” but does anyone here really think these countries are doing much developing?
