PPP is just them saying "when everyone's money is translated onto a standard playing field"--kind of like how the salaries are higher in NYC, but a sandwich also costs 3 times as much so you're not really making as much as you think you are. They've calculated how much actual buying power each country has.

As for the rich sliver to the right of the U.S., I'd guess a small hideout of billionaires that is only technically a sovereign nation--maybe an island owned by Richard Branson, or Vatican City, something like that. To the left of Ethiopia could be any number of tiny, dirt-poor countries that they figured folks wouldn't recognize as readily.
