Why? Should folks not try to maximize these unprecedented times in pilots' favor, if some portion of pilots say they want more non-monetary QOL? If my business partner and I have unprecedented year and quadruple our income, and he takes 90% off the gains and I take 10%, do I have grounds to complain?

It's hard to even comprehend how much money Delta is making, just as much (or more) on the backs of pilots hired in the last 5 years as 25. I don't begrudge anyone at any level seeking ways to channel those gains into their quality of life in whatever means they find appropriate.
