Is there any evidence, other than these people using unethical methods to get hired on initiall at companies, that they didn't earn the raises they received?
I don't have any evidence, but that's the premise of the article. Whether it is evidence based or not was not the topic of my comment.
But to answer your question subjectively, yes, in my experience cheaters will cheat. If they used unethical methods to get hired that's a strong indicator that they will also cheat their way to raises and promotions.
