I certainly does not work as hard as the cleaning lady getting up at 5 am to clean my desk. I just sit there typing lightly on my ergonomic keyboard, in my air-conditioned office and in the end, I will probably end better off, even though she might have crossed a deadly desert to come here and won't see her relatives for a long time. I just have the chance of being born around.
Hard work == success, is probably a variation of the just world bias [0]. It provides a reassuring and motivating narrative, but in the end, it is quite simplistic. I am not saying that hard work is not a necessary condition, but it is far from being sufficient.
Another example : with all the discussions about European debt, it has been reported multiple times that on average Greeks were working much longer that Germans. It does not do them much good.
