ALL Pilots should be required to do a shift in an ATC centre at least once a year that encompasses peak time, not the bull****
PR visit that you sometimes make now.
ALL ATC's should be required to a famil day, sitting in the cockpit for the full duty day that includes at least one flight at peak time into a major airport, not a single famil flight that doesn't see what the crew have to deal with for a full duty day.
Guess why this doesn't happen now & will never in the future?
