I’m Gen X and I can tell you from experience that that is mostly accurate.
We’re the generation that was born, came of age, and entered the workforce when Boomers were still far from retirement age and hording all the good jobs. We had to all go to university to study for the leftovers.
It was the generation after us, that second round of kids that you talk about, that came of age and started going to University right around the time that Boomers began to retire, leaving all these well paying jobs for them to pick up now that us X’ers had already settled on the crappy jobs.
