Dumping sewage into a creek is an externality that is bad.
Someone preferring to live in a suburb does not mean they're generating externalities at that level.
The very reason I pushed back on the comment was because of this black and white thinking.
Saying
> The fact that people dump their sewage into the creek instead of paying for proper sewage treatment/disposal suggests that there's something desirable to _them_ to do the easier and cheaper thing. Of course!
seems condescending to me. As though "those" people don't have the character or moral rectitude to live in the city. Maybe I'm reading in more than you intended.
