North Korea is one of the most unequal countries on the planet, so that's not a very good example. In fact they aren't even officially committed to equality, never mind how it works in practice. They dropped any leftist rhetoric in the 1990s, and now are a country based on the "Juche Idea" (a kind of idiosyncratic religion) combined with the "Military First" economic principle (that resources should be unequally divided, with the majority going to people connected with the military).

Yeah, I'm not really sure of the political message of the comparison. It's not surprising that wealthier people live in nicer areas with more greenspace....

Income inequality is not the enemy - in fact it is what incentivizes our economy and ultimately builds wealth for everyone. Corruption, lack of opportunity, abject poverty - those are the problems.
