I'm going to address work from home first because I think its already settled. Whether companies want to admit it or not, the general public now sees work from home as a benefit that converts to actual money. What this means, is its become an expected benefit in certain industries and its never going back. Companies that force large groups to come onsite arbitrarily are finding the negatives far outweigh the positives, as they now need to hire massively. The one caveat is companies that just use return to office as a way to fire people.
Essentially, its a right we benefit from now, although shitty companies will continue to do shitty things.
For the rest, ive yet to see a single person explain exactly how a city built for cars with very limited public transport, can effectively be changed into a public transportation/biking/walking city.
I'm not an architect or anything, but dont we need to move buildings? Destroy massive portions of cities? I dont know the answer but my feeling is its not talked about much because there aren't any good plans.
Maybe we need to essentially create new big cities so that we have the opportunity to plan their building without cars.
Maybe we could wait for people to abandon cities to the point they are vacant enough we can shuffle people around until renovations complete?
Edit: is it wrong for me to think the government should be negating the negatives of these transitions? For example with the shuffling idea, the government could cover the costs of forcing people to move, even if it still is relatively close by. Maybe even make it fun, can choose groups of temporary housing near friends and family or coworkers if you like them. Cash infusions?
