If SOs are to be the majority group, it’s because of company penny pinching and willingness to compromise safety for cost savings (= managers’ bonuses) through double SO crews. But someone still has to eventually train and upgrade you, and line FOs and CNs theoretically have to mentor you.
If you are ‘local’, you have received free training, without doing the hard yards in General Aviation or the military, that foreigners would give their left ball for. In return, you accepted the crap conditions you joined under, so don’t cry me a river. STFU and pray to golden haired baby Jesus or whatever you believe in that market forces and the hard work and sacrifice of your colleagues will improve your lot.
