Some generalisation is there in an opinion, Physcial efforts are more painful. Once you experience the mental challenge in its exact way, then only one will have the mind and willingness to accredit and part with a pay based on Knowledge and skills. More importance is there for the efforts & skill taken for completing a job than on the utility of the job from the payment point of view.........
