I believe these positions are a percentage of all white collar positions, and that this percentage hasn't changed much in the last few years. Technologically, there's been no major advance that makes working from home any better than it was in 2008. The only thing I can think of is the increased prevalence of video chat. But, I can't imagine that the former lack of free, reliable and high quality video chat is what was keeping employees in the office. Telepresence robots are little more than a novelty right now (imagine trying to lead a whiteboarding session with one of those...). To completely eliminate the handicap of working from home full time, we would need some very convincing virtual reality.
