Why didn't hereditary nobility develop in America?

American immigrants began in Mayflower, England. The earliest immigrants in Mayflower were poor people and English expellers, so these people were pioneers and had no chance to develop into upstarts. When British and French immigrants began to immigrate to the United States, they brought state management to the United States, but gradually the new immigrants could not stand the exploitation of these British nobles and the war of independence, and drove all the British nobles out of the United States, and the east coast of the United States became independent. On the day of independence, the * * * peace system was established. Under the electoral system, hereditary nobility will no longer be developed. However, there is a chaebol family like a nobleman. The United States started from thirteen states and expanded to fifty states through purchase and war. * * The peace system has not wavered, so there is no hereditary aristocracy;
