Yup. When the demand for pilots exceeds supply (if it ever does) then things will change and wages will go up directly (compensation increases) or indirectly (sponsored/subsidized flight training/education by employer or whatever) or both. For the past few decades, the supply of pilots has far exceeded demand, leading to low wages and poor treatment of the professional pilot. When/if the lines on that graph change in the pilots' favor for a sustained period of time, then things will change in our favor- and no sooner IMO.
