I agree that those who are cheating to gain advancement in their careers are not only hurting themselves but are hurting their entire fields. It isn’t fair to the people competing honestly when the people in the top spots are there erroneously.
But I have to ask, who are their challengers? Isn’t it usually the people in the bottom spots who are jealous of the successes of the people at the top? Maybe if the challengers trained a little harder in their fields and worried a little less about the people in the number one spots, they could achieve their own victories and not have to worry about how those people got there to begin with.
Of course, that doesn’t solve the problem of writers citing sources that were plagiarized to begin with, but it’s a start.
