Military?

They aren't paid to be pilots, they are paid to be military officers. On exactly the same pay scale as other officers (some of whom in other specialties also get extra hazard/hardship pay). They also pay targeted retention bonuses to try to minimize excess attrition when the airlines are hiring but that only goes goes so far (they cannot offer airline-level pay, and most certainly not to age 65).

Civilian pilots? The airlines set the pace there, corporate employers have to pony up quite a bit to attract and retain folks who would be competitive for major airlines. In fact they are feeling the pain right now. You're going to see the bottom of the 91/135 barrel go away for at least a few years.
