This could mean the end to the USA based airline system. The same thing happened to the US shipping industry. Today, ships are based overseas and the crew is primarily South island or third world country citizens. The Officers are Dutch or English and other first worlders (Look I made up a word like GW Bush).
I can imagine an industry where all crew are foreign nationals except the captain. The captain could also be replaced but the airlines may not want an English language challenged captain talking to the pax. For all of our sakes, I hope this takes 30 years to happen. Time will tell.
