Okay, but let's be real about something you glossed over: not every trade is the same, and your electrical business success isn't universal. I know three people who got into HVAC training programs, and two of them got injured within five years and had no safety net because they didn't have union backing. The physical toll on your body is real, and trade work doesn't always come with the pension or healthcare benefits that white-collar jobs do.
I'm not saying you're wrong about the credentialing system being broken. You're absolutely right about that. But I think there's a risk of swinging too hard in the opposite direction - pretending that the four-year degree path is the only corrupt system when trades have their own exploitative structures. Some contractors work their guys ragged. Some apprenticeships are glorified unpaid labor for years.
Maybe the real issue is that we pretend there's one correct path at all. Some people love intellectual work and academia. Some people love working with their hands. Some people need stable benefits more than they need earning potential. Instead of dunking on the university system, we should be asking why we've made it so financially risky to choose anything.
