Well if the question is will corporations voluntarily do the right thing for safety and fair wages, I surely would not bet on it. First and foremost they act for the best interest of the shareholders in the short run, mainly looking to boost stock prices. If and when airplanes start crashing due to a lax safety they run for the hills and file bankruptcy. While not all corporations are poor citizens, enough are which is why the industry needs some regulation. Again, it is like an ILS that has run full stop- nothing happens as long as the needle stays near the center.
