This has nothing to do with education. It’s commentary on the academic job market and how professors expect post docs to work for “exposure.
Ngl, I did not actually expand the picture to see the caption. I just saw the main image about knowledge. Post-docs absolutely get fucked and I do feel bad for them.
I quit one year into my PhD because I was miserable in grad school. I have to assume most post-docs have some crazy resilience or some kind of mental issue/trauma that keeps them going and going. I guess that’s probably true for most people but post-docs do some seriously hard mental work and basically get shafted the entire time (at least in the US).
