Now I'm not the smartest guy, but the thought occurred to me...
What happens when these companies find that they can have their workers "work from home" and produce results comparable to having them work "in the building"?
Wouldn't it be cheaper to keep the workers AT home, then close the now-unneeded buildings?
And then, justify paying the workers LESS, because (after all) they don't require as much as they did when they had to commute back and forth "to work"...?
