I think some companies will realize that they don't need quite the same number of offices and making everyone go to one place everyday to work makes little sense. They'll also realize they can probably do without some people (who only existed to supposedly make the people in the office "work").
Most people are capable of working without constant supervision and micro-management and will in fact do it better when it's gone. Obviously, not all, but some, maybe more than people realize.
It's only when you stop doing something that you can see it for the waste of time it was. Commuting to work? You can do so much more with your time when you don't do that.
People might discover that looking after and teaching their own kids is actually rewarding, and it makes no sense to kill yourself working just to be able to afford to pay someone else to do it.
State schools and universities have to take a hit - their Ponzi scheme of faux-education / indoctrination doesn't make sense.
Some people will gain, others will lose, I don't expect everything to return to exactly as it was.
