Work at office: hundreds/thousands of multi-ton SUV's try to get to the same place at 9am and 5pm; parents are absent from their children and each other half the day; real estate values near offices spike insanely; if people commute by bus/train they have to sacrifice even more hours, and also, share space with crazies and you still have to move a massive amount of physical stuff around.

Work from home: some electrons & photons move.

Which one costs society more?
