20 years ago I knew a bunch of people in their teens and early twenties. Now I know a bunch of people in their 40s and I couldn't tell you what the teens around me are doing. Are you sure you're not just picking up on the fact that you're 20 years older now?
My point is 20 years ago I had zero middle class neighbours that fell into this category and that number is the same today. I suspect those numbers represent most people's experiences as well.
The article is suggesting that there is a delta between the past and the present. My argument is there is no delta. There were always nearly zero people in this category.
