Jack London,
The Iron Heel
(1917)
“ We will say, for the sake of round figures, that the total production of wealth in the United States in one year is four billion dollars. Then labor has received in wages, during the same period, two billion dollars. Four billion dollars has been produced. How much of this can labor buy back? Two billions. There is no discussion of this, I am sure. For that matter, my percentages are mild. Because of a thousand capitalistic devices, labor cannot buy back even half of the total product. ”
