Productivity gains seem to be dropping and one theory is that companies are getting larger, but aren't able to pickup efficiency/new value generation boosts from acquisitions like they once were able to (at an economy wide scale, not talking about the acquisitions of any specific company or even sectors here). It is difficult to make any certain conclusions here though. But if true, they will have to care sooner or later.
