This was roughly speaking my first thought as well. I thought "Well we always laughed at the sci-fi depictions of people with big cans of air for sale, come pay for premium filtered air ... but this is how that all starts, isn't it. Rich people pay for an air that might make them think 10% faster, then as it starts to normalize to the middle-class, they care less and less about pollutants in the air and eventually we just regard that as a poor-peoples' problem."
