I'm gonna be rich!

Here's news that shouldn't be news.  Assholes make more money than nice guys.

A new study finds that agreeable workers earn significantly lower incomes than less agreeable ones. The gap is especially wide for men.
The researchers examined "agreeableness" using self-reported survey data and found that men who measured below average on agreeableness earned about 18% more—or $9,772 more annually in their sample—than nicer guys. Ruder women, meanwhile, earned about 5% or $1,828 more than their agreeable counterparts.
"Nice guys are getting the shaft," says study co-author Beth A. Livingston, an assistant professor of human resource studies at Cornell University's School of Industrial and Labor Relations.

That bold part is my emphasis.  I think "nice guys get the shaft" works better than "nice guys finish last."

"Nice Guys Get The Shaft." Pimps throughout the ages have known this rule, which is why Ronnie here keeps his pimp hand strong, beeyotch.
