What he says is true.
As kit becomes more and more expensive and required to do more and more things the numbers purchased get substantially less.
The consequences of this is that there are less trained to use and the loss of one is greater because less of a fleet in the first place.
The desire of the powers that be to have more missiles and now more UAVs will no doubt end in a strange situation. Potentially FJ pilots in service and flying will become as rare in late 2030's as fully trained Fighter / Bomber pilots in 1930's.
