Go away...
If corporate wanted to reduce the desire for remote - they would have smaller satellite campuses outside the great automobile slums of America.
The wealthy don't care about efficiency, they aren't being rational about this.
They go into the office - see an empty building and say "this is wrong".
But they put the cart before the horse - they should say "why is my company operating just fine without office space?" - that should say something about how horrible open offices are for productivity.
The intangibles that come with in-office work could be addressed by augmented reality meetings (a headset costs a lot less than a year of gasoline).
The ONLY problem I see that isn't addressed with remote work is junior development. This again could be addressed by much smaller campuses and augmented reality.
