As time went on and technology advanced, more and more workers sewed clothing in large factories. It was loud and crowded, and the hours were long with few or no breaks. Workers often had to pay for their own supplies (needles and thread) and were sometimes injured by the machines. Many of these factories also employed children and teenagers. Some of the money workers earned went towards food, lodging, and cultural activities, but much of it was sent overseas to help relatives living in their home countries.
