Residents of Swiss financial center Zurich know that their country has more to offer than world-class chocolate and precision watches. They can now brag that, on the whole, they earn more than anyone in the world. Zurich-dwellers rake in $22.60 per hour in average net pay, according to a wage survey released August 19. The runner-up city is less than 200 miles southwest: Geneva, where jobs pay $20.40 per hour.
