You are way out of touch regarding OJTI duties, it's an onorous responsibility being a mentor to any student atco, if they "f*ck up" it's your licence at risk.
The vast majority of employers (even Serco!) recognise this by rewarding atco's willing to train others, a minority don't - mine included.
I happen to enjoy the challenge of being responsible for someone's training and progress, and take a great deal of satisfaction in seeing them through the validation, but if they don't make it, or screw up shortly afterwards, questions are asked not only of the LCEs but the OJTI as well.
In any industry, increased responsibility is rewarded with increased renumeration, and I don't see anything wrong with that.
