An equalizer, yes. They lift up those with little skill, and they drag down the top talent.

This is a practical effect by which top talent is neutralized. Where they should lead people, they talk to models instead. ...now you have a generation of leaders that don't deal well with any real emotion or disagreement. They can steer but not lead -- many no longer believe in the value or efficacy of leading people.

Of course you are also right to point out that many people in "traditional leadership roles" have been content to sit back and steer rather than heading of the charge. I still wish to command both talents: steering and leadership. I refuse to flatten myself out to fit in better, and I always have.
