How did the structure of social classes in france lead to discontent

Structure of social classes in France lead to discontent:

Because the third estate was the group which paid the most taxes. Furthermore, due to the fact the estates-general gave each state a vote, the third estate being the odd one out could never get enough voting power to do anything.

The first class was clergy, the second was the nobles, and the third was the peasants and commoners. The third class were playing all the taxes and worked for the first two classes. The third class also had the least power and could not be accepted in the first two classes. In the system, most of the rights and privileges were given to the classes. It was the ultimate system of control for medieval society.
