Test cricket is all about getting 20 wickets guys, not really the "economy". It doesn't matter how many runs he concedes as long as he picks up wickets at regular intervals. We have Nazza!, Big Z and Nayeem, so it really doesn't matter what the Windies put on the board.
"O people, we created you from the same male and female, and rendered you distinct peoples and tribes, that you may recognize one another. The best among you in the sight of GOD is the most righteous. GOD is Omniscient, Cognizant." (49:13)
