There would be zero binding arbitration. That takes sections of legal law and proving beyond common sense. Look at any LCC vs a major in payrates on the -88 or -318/19/20/757. It capitalism. That's life. It goes both ways. The nlrb is a long shot at best at this point to say "airline abc pays 987 an hour and we get 123; and mgmt doesn't agree, yet we staff it..". Apples and oranges. Airline A has billions in profit, airline B is fighting a loss. That's a free economy. Airline A may be business people with a reliable schedule vs B, or flights every day vs once a week, or snacks vs a swipe, or bags, or; now I'm mad.
Lcc's make a profit. Majors make a bigger profit by many factors. The majors win by reliability, perks, and overall schedule. That's economy of scale, and the american way. It's also known as capitalism. Show up to win or be beaten. Thats life in a 5k race or life in general. If it makes you feel better, I got killed in my age group for a turkey trot and get to try again in st Jude. Life sucks, you pay taxes, then you die. Such is life. Either get onboard, or yell and scream all the way through. Your call, it's your time wasted.
Look big picture. Pick your path, and enjoy life. Thinking the govt will give you something is amazing, like social security for millennials. Sounds great, not happening as hoped. You create your own destiny, on your choices alone.
