First, capitalism itself is a term popularized by Marx and socialists, as a way to demonize wealth and the wealthy. The industrial era working conditions was nothing new, most of human history was predicated on lax and dangerous working conditions. New technologies and industries simply created new ways and bigger scale endeavors. Compare any industrial era project or career's condition statistics to say... the Great Wall of China, or Pyramids. Mass communications (books, newspapers, etc) allowed the socialist liberalized media to paint a picture of supervillan wealthy people and societies.
