Answer:
European investors largely supported American entrepreneurs. American cities grew at an increasing rate in the 1800's. This was the result of large number of people migrating from rural areas in search of work. Industries were increasing day by day, so was the population. And, to earn profits, American businessmen made an investment in goods.
Entrepreneurs fuelled industrialization and they also helped encourage innovation in the late "1800s". They gained from "laissez-faire policies", which allowed them to work under minimal government interferences. They were largely supported by European investors.
