There is still a side benefit to the workers that must work on-site: the white-collar work that can be done at home no longer needlessly clogs the roadways with cars every arbitrary 'rush hour'. Many of my blue-collar friends loved the early months of the pandemic where they had zero traffic jams and other commuter headaches to deal with.

Less pollution, less traffic fatalities, less energy use, and more money flowing to remote areas (like where a lot of infrastructure is typically located). All good things for everybody, even if the benefits of working in your PJs are unevenly distributed.
