The benefit doesn't just exist for no reason. It only exists because of limited resources. When resources are not limited we don't display aggressive behavior.
We are not living in a time of limited resources therefore it is actually evolutionary detrimental for us to be aggressive. It's not a coincidence that our popular culture de-emasculates itself bit by bit every decade. It's because we live in plentiful times and our behavior (which is conditioned through natural selection) reflects this.
