How did the new working class of the industrial revolution differ from working classes of the earlier, farm-based economy?

During the Industrial Revolution, people from the countryside flocked to cities and factory towns looking for a better life. They wanted to make more money to support their families, and they hoped to move up in the world. They believed that they had a wonderful opportunity to try something new and take part in an era of wonderful progress. Unfortunately, disillusionment soon followed when workers realized that their new life wasn't at all what they thought it would be.
