Why louis xvi was taking high tax from common people
Answers
The definition of a “common people” was historically such, especially under the rule of Louis XVI (1772–92) that it had nothing to do with how wealthy or poor you were in reality, but whether or not you were part of the First or Second Estates (an estate was defined as the theoretical division of a country's population [1]), of which the highest ranking Clergymen, and the Nobility were part of respectively.
Literally anyone else meanwhile, was part of the Commoner’s group, or “Third Estate”.
An artist’s impression of the Status Quo in France at the time, as interpreted by the Third Estate (they saw themselves as being unrightfully oppressed by the privileged classes):
98% of France’s 27 million people were part of this so called Third Estate, and it included the lowliest ranking Priests, to the poorest of the Peasantry, to the wealthiest of Bankers, and most learned of Intellectuals.
18th Century Demographics of Bourbon France (Source: Colin Jones, The Longman Companion to the French Revolution, pp. 287–8):
Thus, for simplicity’s sake, I will only cover the following three groups of people belonging to the Third Estate: the Peasantry, the Urban Worker, and the Bourgeoisie “Middle Class”.
