How cotton is made

Mill owners found ways to reduce those costs first by employing women and immigrants who were often paid poorly then by employing young children in the factories After oppressive labor practices were largely halted many factories moved to the South where labor was cheaper Unionizing efforts affected the profits of those mills Today a fair amount of cotton is woven outside the United
