The shamelessness with which gringos in Medellín relish in their financial advantage puzzles me.

“I worked hard for the money I’m spending.”

I’m sure you did, but not even close to as hard as you make your Colombian counterpart work for it.

“But I’m helping people by spending my money here.”

If you are serious, stop trying to 1. find the cheapest way to 2. satisfy your preferences and desires, and find ways to make your undeserved comfort alleviate other people’s undeserved discomfort.

Or at least be ashamed if you don’t. Carechimba.
