The productivity of some workers may be rising, but not all. For example, with all the investment in government we've had, government should be very efficient.

The productivity of some workers may be rising, but not all. For example, with all the investment in government we've had, government should be very efficient. Government services such as roads, transportation, education, care for the poor, wars on brown people, business regulations, prisons, etc should be very cheap right? Or could it be that as the private sector increases its productivity, the public sector correspondingly consumes/wastes more?
