Why does it cost significantly more for a trip from Nicaragua to NYC than vice versa?

Why does it cost significantly more for a trip from Nicaragua to NYC than vice versa? - From below of illuminated interior of Grand Central Terminal station with high decorated ceiling and big windows with pillars in New York USA

When looking up flight prices, I noticed it costs ~ $365 roundtrip from NYC to Managua, Nicaragua and ~ $700 roundtrip from Managua to NYC.

I assume there are similar situations from other major airports in South America.

Is this because NYC is a very popular destination whereas these cities in South America might not get as much traffic?

Also, is it legal (although I know in this situation you wouldn't be saving money) to buy a round trip from NYC to MGA and only take the return flight to get to NYC from MGA?
