Success (by which most people mean financial success, fame, or winning in some competition) is certainly worshipped.
However, just being "a hard worker" in itself is considered a virtue by many people.
I hesitate to call it the Protestant Work Ethic or the Puritan Work Ethic, as it's far from limited to Protestants or Puritans, but that's really what it is. The harder you work, the more virtuous you are considered to be, and working less is considered sinful or lazy (in other words, unvirtuous and blame-worthy).
