Answer:
looking for personal freedom and jobs
Step-by-step explanation:
Since the industry started to develop in the United States, the interest among the people to migrate to it increased even more. The reasons for this were that the United States had industry that was growing very quickly, so labor force was demanded, thus the job opportunities were plenty. Another reason for the migration was personal freedom. The United States were seen as the country in which the people can express themselves freely, and that if they work hard enough and are capable enough, they can easily progress and became part of the higher class, which of course was very attractive for the ordinary people.
