What did henry ford do in the roaring 20s

There are a lot more things that he did in the 20s but I just gave you one.

He introduced the Model T automobile as an owner of the Ford Motor Company. He became the richest and best known man in the world at that time. He produced many cars that were not so expensive using the assembly line. His workers got paid way more than anybody else. His famous invention of the car cost $850 which was a reasonable price for back then. 

Henry Ford (1863-1947) was one of America's greatest businessmen, the founder of Ford Motor Company and the man largely responsible for initiating the era of mass-consumption and mass-production in the American economy. Ford's innovative business practices, including standardization, the assembly line, and high wages for workers, revolutionized American industry.

Directly or indirectly, the economies of all 13 british colonies in north america depended on slavery. by the 1620s, the labor-intensive cultivation of tobacco for european markets was established in virginia, with white indentured servants performing most of the heavy labor. before 1660 only a fraction of virginia planters held slaves. by 1675 slavery was well established, and by 1700 slaves had almost entirely replaced indentured servants. with plentiful land and slave labor available to grow a lucrative crop, southern planters prospered, and family-based tobacco plantations became the economic and social norm.
