Gunga, this is more how I see it:

1500 hrs --> more experienced candidates --> better captains --> increased safety

but the smaller effects of this may be:

1500 hrs --> levels the hiring playing field --> pilots with the choice go to better carriers --> bottom feeders need to raise QOL to get applicants instead of just lowering mins --> pay raises slowly --> by the time I retire, I have enough money to hire Megan Fox's daughter to star in my "movie"
