Companies are paying the increase in productivity to the professional-managerial employees who are actually more productive because of technology, scale, etc. and not to the masses whose productivity is the same as ever.
Even when we talk about redistributing this increase, we mostly talk about redistributing it from the professional-managerial employees, who populate the higher personal income tax brackets, not from the companies themselves (corporate tax) or their owners (wealth tax). If you are right that companies and their owners are pocketing it, then we are looking for it in the wrong places. But it seems like it really is largely going to the PMC.
