Sonnendec,
Its the people who run ATC that are complacent. The controllers can only do as good as their system or training allow. In the past when I have submitted an Air Safety Report about air traffic control related incidents, the chances of a reply are zero. Believe me I would rather not have to complain. The problem of people ignoring the warning signs are all too evident..... an example of this is running in the courts as we debate this.
