" Because, to do manual work now, means in reality to shut yourself up for ten or twelve hours a day in an unhealthy workshop, and to remain chained to the same task for twenty or thirty years, and maybe for your whole life.
It means to be doomed to a paltry wage, to the uncertainty of the morrow, to want of work, often to destitution, more often than not to death in a hospital, after having worked forty years to feed, clothe, amuse, and instruct others than yourself and your children.
It means to bear the stamp of inferiority all your life; because, whatever the politicians tell us, the manual worker is always considered inferior to the brain worker, and the one who has toiled ten hours in a workshop has not the time, and still less the means, to give himself the high delights of science and art, nor even to prepare himself to appreciate them; he must be content with the crumbs from the table of privileged persons.
