Another user made a good analogy in a recent thread, and they said something to the effect of: it's like self driving cars, the computers can do 99% of it when conditions are perfect, but it's the 1% that can't be programmed that has life and death impact.
Or like a coworker said: a monkey can do our job 99% of the time, it's the other 1% where we earn our pay.
If I had a M-F/9-5, I wouldn't have the same issue about the pay, however there are 15,000 controllers across the U.S., and none of them have a M-F/9-5. If the U.S. airspce was restricted to M-F/9-5, then our economy would grind to a halt, billions if not trillions would be lost in productivity, our military would be tied with its hands behind its back, etc.

I used to recommend ATC as a career for people, not anymore. I've heard of other controllers telling people that they convinced to become ATC that they're now sorry that they did. When talent leaves, and talent recomends to other talent to choose a different career, there's going to be problems down the road. The adoption of technological advancement over the past several decades in U.S. ATC has been abysmally-slow, I'm afraid it won't make up for the brain drain.
Pay a little more money now while there are still good controllers that can train future good controllers, or pay a lot more in other ways later when the talent is gone and can't come back.
Opinions are my own and not necessarily that of the Federal Aviation Administration.
