Lesson 1: The Rise of Industry

John D. Rockefeller revolutionized the oil industry with his company, Standard Oil. He used a strategy called Horizontal Integration, which meant buying out or destroying all his competitors to create a Monopoly. By controlling nearly all the oil refineries in the country, he could set prices as he pleased.

Rockefeller's ruthlessness allowed him to build immense wealth, but it also sparked fear. Critics called him a "Robber Baron," arguing that his control over the market crushed competition and hurt consumers, leading to calls for government regulation of Big Business.

Andrew Carnegie dominated the steel industry using a different strategy called Vertical Integration. Instead of just buying other steel mills, he bought the iron mines, the coal fields, and the railroads needed to transport his materials.

By owning every step of the manufacturing process from the ground up, Carnegie could produce steel cheaper than anyone else. This efficiency helped build the skyscrapers and bridges of modern America, while Carnegie promoted the "Gospel of Wealth," arguing that the rich had a duty to give back to society through philanthropy.

As corporations grew, individual workers lost power. To fight for better conditions, Samuel Gompers founded the American Federation of Labor (AFL). Unlike more radical groups, the AFL focused on practical goals: higher wages, shorter hours, and safer working conditions.

The AFL was a union of Skilled Workers. By organizing only those with specific trade skills, they had more leverage in negotiations. They used strikes and collective bargaining to slowly improve the lives of their members, setting the model for modern labor unions.
