>Not every talented person is motivated by greed for personal wealth and status.

What I said doesn't require everyone to be "motivated by greed for personal wealth and status". The effect will still be present even if only a fraction of people behave that way.

>Actually most aren't.

Source?

Forget about money - do you know a lot of talented people who are happy working with people who don't share the same motivations?

Of course? The most famously talented people their lives teaching, mentoring and otherwise trying to lift up those around them. Could any person be an effective leader if they didn't enjoy the challenge of working with people with different values and motivations to themselves? I've certainly never seen one.
