How did France social divisions on the late 1700s contribute to the French Revolution

In the late 1700's the people on France were in a very bad position, and the reason for that was the greediness from the aristocracy, the segregation by class, and living the majority of the population on the verge of existence.

Most of the people were poor, thus in the lowest class in the society. They were sick of being treated like animals by the aristocracy, despite the fact that they were the ones that created their wealth. Also, their kids were not able to go to schools and study because it was very expensive, so they didn't had any chance of prosper. The institutions were not available for the ordinary people as well.

Than the time came when the revolt reached its peak, and the people decided that it's enough. They had a leader that promised them what they wanted, and they took down the aristocracy and the king. That leader was Napoleon Bonaparte, who was beloved by the French people because everything he promised, he actually did it, unlike the other previous leaders.
