About rewarding grunt work more, that's also the idea on which the work is distributed in the utopian community described in Skinner's Walden Two:
"About four labor credits are required per day, which translates to anywhere from two to six hours of work depending on the number of credits that are awarded per hour for a given job. Unpleasant jobs, like cleaning sewers, are given higher credit values than easy ones. Members are free to choose their jobs each day, except those that require special training, like medicine."
I recommend that book. (I read it when I was a teenager, more than twenty years ago.)
I do not understand your comment. Do you know of any salary whose amount depends on how pleasant/unpleasant the job is? The idea here is that unpleasant jobs, i.e. jobs that most of the people do not want to do, are paid more. I don't think this is the case in our current society.
