Roaring Forties, I covered that in post

Two completely different sphere's. Governments can simply tax citizens directly & indirectly (taxation via inflation), in addition to actually spend more than they earn (deficits - the bill handed to citizens not yet born) to pay for this extremely high quality training. Not only that they can force the trainee's to continue to work for them by force (return of service).
Airlines on the other hand cannot use these mechanism to absorb the cost - retention is through large debts to the organisation or regulation (MPL). This is why you are unlikely to see training of anywhere near the military standard in a commercial sphere. Therefore, the only mechanism available to regulators is some arbitrary hour minimum.
