“to escape poverty” is a subset of “for commerce”.

Some of us don’t go to cities at all if they can help it. My visit to a city is usually because I was dragged there by somebody else, or because I’m traveling through to get somewhere else. I’ve visited enough cities (in every continent but South America, and Antarctica obviously) to know you all can keep them.

I recently moved out of the city too, and everything in the article resonates with me. It's just that people that move into the city usually do it to get a better job. If you have been born there, yea, it probably feels like what the author said, you don't even realize.
