Why did the third estate resent in 18th century in France?

The Third Estate in 18th century France resented their situation due to their heavy taxation and lack of political power despite being the majority of the population. While the nobility and clergy (the First and Second Estates) enjoyed privileges and exemptions, the Third Estate bore the financial burden of the monarchy and state. Additionally, they were frustrated by their limited representation in government and their exclusion from decision-making processes. This growing discontent ultimately contributed to the outbreak of the French Revolution.
