I don't think the pay scales are strictly based on a yearly progression AKBeemer. It isn't like they start at Scale A and every year progress on up the ladder. I've read that the FAMs start at Scale G and can eventually max out at Scale I, then if they move into Supervisory positions can max out at Scale K. I'd be willing to bet that the actual TSA agents stacking those tubs with the GED aren't making $153k/year.
