China has proven you can just mass produce pilots at reasonable standard, and they do it at incredible rates like 10,000 per year. All that while still paying them relatively poorly, although well for China. Yes they will employ a few expats over time for exorbitant rates to fill gaps, but that's definitely the minority.
If you think pilot pay will somehow return to the heydays and gravy trains of the 70s through 90s, I think you are very misguided. Other industries employee unions control the tap, in aviation the airlines have almost complete control.
If you can't even negotiate scope clauses to prevent white ant-ing then you have no chance to build T & Cs at majors.
