The tide is gradually turning against the Globalist "free trade push". The next stage of that, assuming Trump goes through with his promises and Brexit actually occurs, is a revisiting of conventional current economic wisdom about the efficiency of private vs. public sector service provider models and that includes Airservices.
Frankly Airservices and CASA are both seriously flawed models. Their proponents tout " Private sector efficiency with public sector accountability" what we actually get is "Private sector rapacity with public sector sloth".
To put that another way, we get the worst of BOTH the public and private service delivery systems
In more detail that means inflated costs as the "business" pays its managers "comparable market based salaries". That means an inflated services charging regime. However since there is no blowtorch of competition, there can be no consumer choice. Then of course, when threatened by events, its employees do their level best to proclaim themselves simple public servants.
Jobs for life and commercial salaries. What happened to the old idea that public servants were paid less because they had jobs for life?
I think the pendulum is about to swing the other way..
