This is one of the best visualizations of this issue. I regularly think back at this comic, awesome!!
And, again, this does not negate the fact that Richard worked hard to get his degree and worked his company's ranks. It should not be about pushing down the Richards of the world, it should be about pulling up the Paulas, and strive for a world were everyone is a Richard [relating to the comic, not all white men or we would be doomed ':) ]
