The Rise and Fall of the Professional Management Class

The discourse, the rhetoric that emerges from this class and their elite to aspirant interests is what's driving a lot of our national discourse. So I guess my question is something like this where like, if we are to assume that the PMC is really on the decline, why are there interests in their rhetoric so forefront in all of the discussions? Is this like, is this the last kick of a dying horse or are there some sectors where the PMP is actually growing in power? The late Barbara and Reich will always be like my household goddess and I respect John Aaron Reich so much for what he's done.
