Maybe. But the more well-off people crawl into cocooned experiences, the less they care about public infrastructure. Look, for example, at how suburbs not only often lack public transit themselves, but work to fight regional transit.
They are funding it less and less. And things like the wave of white flight and suburbanization in the 1960s and 1970s make it clear how comfortable well-off white people are doing that.
In any case, I'm not arguing for guilt trips as a means of solving the problem. Instead, I think the right solution is the bedrock of any community: shared experience.
