Well, it was a widely and strongly suspected behavior. It was never proven, to the best of my knowledge.

Yeah, seems like a behaviour that increased during ZIRP and started reversing when that went way.

At the least it might have been let people grow as much as they can because the money's so cheap, maybe anything is better than nothing.

It's too bad though where junior devs couldn't get access to senior mentoring capacity that might have been needed.
