Answer:
There are many reasons why industrial growth affects the distribution of wealth. Since products were now made from machines instead of hands, it led to an increase in efficiency and production. There were more products being produced, more goods, then, they got sold in lower prices. There are also other factors like improved wages/salary(s) and migration of people from rural to urban areas. In the U.S, the upper class became more wealthy and rich, whereas, the lower class became poorer and lived in poverty.
