Answer 2

Beliefs of the newly emerged social classes of the late eighteenth century:

The term 'class' came into prevalence from the nineteenth century. Until the eighteenth century, the people were categorized based on the heritage and economic system of the family. The industrial and political revolution in the eighteen century gave rise to a new 'social class'.

This class distinguished people in terms of labour or production. The capitalists or high-skilled workers correspond to the upper class in society. The difference in income levels decides the people in middle or lower class.
