Look at the mills in Gastonia, NC in the 1920’s and the mines of the same era. Child labor, workers exposed to carcinogens, unbearably loud noises, dangerous equipment, long hours for little pay which, for mill workers, went to the company store which they would then become hopelessly indebted to. The mill owners, at one point, decided to try and get more output while, at the same time, cutting 50% of the work force. They thought they would just make the remaining workers work harder than they already were. Laborers were blocked from protesting and hounded by gangs of thugs which included some police involvement; look up the death of Ella May Wiggins.
I would throw in the for-profit prison system, too.
In short, when companies decide it’s OK to destroy the environment and treat people as throw-away objects, it’s gone too far. Pope Francis said, "When money, instead of man, is at the center of the system, when money becomes an idol, men and women are reduced to simple instruments of a social and economic system.”
