The only thing governs pilot wages and conditions is supply and demand. No different to any other job or business enterprise. Regional pilots in the USA have some of the worst working conditions for so-called professionals in the western world. Because at any one time there are hundreds if not thousands of pilots on furlough and because it is still relatively cheap to learn to fly in the USA. Wages here are not good but at least the duty time rules are better and we all get a whole lot more vacation time.
Despite all the hype about a looming shortage, the shortages will be in places many pilots don't want to work, so the domestic scene here like in the USA won't improve much whatever noise we make. All we can do is chip away, and flex a bit more muscle during any temporary shortages.
