Yes, my expectations are based on my experiences of people prioritizing their family's health above all else, assuming they have income security. If I was in a situation where my children are breathing in air I thought was harmful to them in the long term, and I had the ability to move somewhere where they weren't being harmed, I would prioritize that above all else.

I would be shocked if I met someone who would sacrifice their family's health if they had a decent option where they wouldn't have to. This probably doesn't apply to most people, as they might have to weigh trade offs such as moving away from family and whatnot, but the person who wrote the article is obviously earning far above most, and can afford to easily move.
