Is this compensation? Is this satisfaction with what you do? Is this ability to pay your bills and save enough? How much does one need (what's enough)?
This is all complicated and we tend to focus on compensation. That's why so many people stay in jobs for the pay while they hate the work.
There are lots of good quality jobs out there if you expand your definition beyond "highest compensation". I know people who switched and were much happier in trades. They felt far more satisfied, could daily see their accomplishment, and meet their bills (and then some).
Where did you get your view on good quality careers from?
In the context of this thread it is (almost) all about compensation. "Good quality" is in the sense that one can earn enough to "meet their bills (and then some)" and also weather a major event (such as a medical event). Satisfaction may or may not apply.
