The Industrial Revolution

The Industrial Revolution aided in the creation of a middle class. What were some of the distinctions of the middle class compared to the poor or the nobility?

There were no differences between the nobility and the middle class. The nobility was the middle class.
They were often managers, lawyers, doctors, or industrial owners who married for companionship rather than power, educated their children, and often hired at least one servant.
The middle class lived in extremely expensive homes with gilded fixtures, preferred the single life more than marriage until age 50, avoided public life -especially politics, and sought profit more than anything else.
