I worked in a gated, enclosed, guarded community in a Central American country with a bunch of expats - British, Canadian, American - and saw nothing but abject poverty outside of our small enclosure. Everything was delivered. McDonalds, Pizza Hut, local food, drinks, newspapers, groceries...

We had transportation to the local office and I saw much the same as you, but in way worse conditions.

It affected me just the same as you. I didn't last very long before taking a remote assignment and going back home.
