I think that choice b is a good response to this question because as the Industrial Revolution progressed people were taken out of their homes and into factories. They used to spend hours making one item but now the machine they operate can make one in a matter of minutes. As you pointed out in class some business owners might be concerned with the quaility of their product but I was under the impression that most just wanted to make the maximum profit by producing as many goods as possible. Finished goods were in higher demand as transportation improved and settlers out west could order these goods through a catalogue. Business owners wanted to sell their finished goods to as many consumers as possible so they would need a lot of products. In addition, the quality of the products were probably not as good as before in many factories because factory owners looked for the cheapest workers, not the most skilled.

"Industrial workers were employees rather than producers, and repeating specialized tasks made them feel like appendages to machines. The emphasis on quantity rather than quality further dehumanized the workplace."
