The main difference in how wealthy and poor people were affected is rich people stayed in power and riches while the poor just got a taste of being able to afford things. The poor people lived in bad living conditions and couldn't make a living  as big companies grew bigger and became more rich off of mass production.

Mass production was one of many new systems established as a result of the industrial revolution. White-collar work and easy jobs meant more people could make money for themselves and more people could spend money on goods. Because of mass production, prices dropped and goods became cheaper to purchase, benefiting the middle and working class by allowing them to purchase more. 

At the bottom of the classes were people who were poor and were sent to work in factories. The upper class people improved by  buying mass produced goods. White collar workers were known as the middle class and were office, and factory managers.  At the top were owners who owned large corporations.  Poor people lived in small tenement buildings in the slums.  In these buildings fires, and disease spread easily so many people lost their belongings or died.

One difference in how wealthy and poor people might have been affected by mass production is that with mass production came more availability of jobs. Competition for jobs kept the wages low so this might not have affected people who were wealthy and just wanted a job for cash for spending, where it could have affected the poorer people who need the job to eat and have a home, but since the wages were low, it most likely was not enough so the wife had to work as well.

Essentially the rich get richer and the poor remain poor.  The rich who owned businesses became even richer.  While the workers continued to get low wages while working in a harsh, filthy, and dangerous condition.
