Unless someone really want to become a postdoc or tenured PI similar to the calling of a teacher, it's really difficult to justify the lower opportunity (time and money) cost of a Masters' or PhD in the US in tech, for example. After just a few years, one can make 250k USD/yr sometimes without even a 4-year degree in CompSci or related STEM field. I honestly feel dumb for pursuing the equivalent of a reputable BS EE/CS when I could've been making 400k/yr in dotcom times.
More power to pure academics who don't pursue money or fame, and instead make an impact.
I am more motivated to find jobs that let me think my thoughts than jobs that maximise my income. People often say well but if you make a lot then you can pay for this. I have found that those that make a lot never find the time to pay for it.
