Do not throw stones before thinking a bit.
I come from a time where salaries and working conditions were extrelemy poor and it is the French strikes of the 70s and 80s that raise the salaries to their current levels, as well as education ( engineer level) and recognition.
In those days solidarity among controllers was the norm , because most of us could not strike, but got some of the benefits the guys that did strike manage to get in the end a bit later...always have.
Today's kids starting in the profession think the salaries and working conditions they enjoy is a fact of life, it was not , people fought hard to get them there.
