Speeding is good
Way too many commentators here would, on being stopped by a policeman for speeding argue -'But it's more efficient for me to drive faster because time is money'.
Because too many people in the world have made decisions in the past that have been biased, we have LAWS that say you can't be biased. Those laws impose some extra cost on society, business and individuals. Just like the 'don't murder people' law inhibits my ability to stab someone and steal their wallet.
