Second job? None of FAA's business how one spends his off time. For 25 years I owned an aviation market research business, it had no effect on my FAA work, except to make me more knowledgeable about aircraft.
The young kids today do seem to burn both ends of the candle, but that is a personal choice guided by their entitlement mentality and buttressed by the union. The pay is great, but damn, the quality of the people has just plummeted. I would never urge a kid I thought highly of to take this job in today's FAA.
As a retired Air Traffic Controller I tend to agree with your thinking. I left before the strike. I was an Air Force Pilot prior to going with ATC. It will be quite difficult to devise a good system even if allowed to. I am glad that is not my job..
