David O. McKay uses "negro" to describe those who reject importance of labor.
David O. McKay, Conference Report (October 1909): 91
Labor is the law, and whoever repulses it as a bore must have it as a punishment: You do not wish to be a laborer, and you will be a slave; toil only lets you loose on one side to seize you again on the other; you do not wish to be its friend, and you will be its negro.
