The business model also seems to be set up in alot of places to take into account a military pension also being paid.
It seems to me there just are not the same number of these chaps coming into the industry.
Also as well I think the MPL was a attempt to break away from the dependence on light aircraft. But the requirement for it to be taken in conjunction with an airline has screwed things up somewhat as the schools need 2-3 times more fresh meat through the door than there are jobs available. And as there isn't enough market for it they are stuck with the expensive twins.
