1. Not when those State sponsored carriers are Circumventing US labor laws. Can Delta pay third world ramp workers from Pakistan $5/day? Can United tell flight attendants they're done flying at 27 thus keeping the FA pool younger and paid less? How's that pilots union working out at Emirates, Qatar, etc.? Feel like you'll be ok if you happen to have a bad day? Management got your back since there is no union? Gonna get that upgrade in seniority order?
2. Let's not forget major ($160 billion) aircraft purchases with gov't money, which is then FINANCED with US taxpayer dollars, at interest rates US carriers can't get.
3. I could go on, but what you postulate is an assembly line worker moving to China to do the same job, taking his job and the industry with him, then wondering why all his old friends back home hate him.
