Final answer:
Napoleon's economic reforms decreased inequality by introducing an equitable tax system and established a more egalitarian social system.
Step-by-step explanation:
The sentence that best describes the effect of Napoleon’s economic reforms on the people of France is: Napoleon's tax system decreased the inequality between the rich and the poor. After the chaos of the Reign of Terror and costly wars, Napoleon sought to stabilize and improve France’s economy by introducing a more equitable tax system where all citizens were proportionally taxed, creating the Bank of France, and implementing monetary policies to support the economy. The Napoleonic Code also abolished noble privileges and ensured equality before the law, benefiting commoners and partially contributing to a more egalitarian social system.
