>So they would live in a neighbourhood full of young people.

Do you know many young people who would love to live in a quiet suburbia over a busy city with lots of things to do? They, of course, exist, but they aren't the majority. I doubt that remote work will suddenly make every young person appreciate the quiet suburban lifestyle, and lead to suburban towns being heavily populated by young people.

Not every place outside a large urban area has to be white picket fences. It can be what we reimagine.

Sure, and we can technically build another Silicon Valley somewhere in the midwest as well.

The thing is, do young people want to spend their youth and efforts "reimagining" this (the effects of which they won't even see, even in the most optimistic scenario, until they are well past their youth)? I know that I, personally, don't. And it seems unlikely that a lot of young people would be willing to latch onto this kind of "opportunity" either.

It isn't even about "white picket fences", it is about the number of opportunities around, which you only get with high population density. Which is the antithesis of the suburban style of living.

If you think young people don't want to completely change the system you are out of touch. Sanders was hugely popular with under 30s. People want change.

they want political change, not physical change. I can't imagine many young people want to give up a bustling city with lots of culture, dating opportunities and things to do for a place thats cheaper with a slightly lower risk of contracting a virus from pandemics that only come around once or twice in a lifetime

Yes but not the change you are describing. Young people reinvigorating small towns was not one of Bernie's platforms so I don't know how it's relevant.

Young people want change. But they still want to move to cities with things to do while enacting change. Just look at the demographics.
