The correct answer is cutting the quality of his products
Andrew Carnegie was a Scottish businessman, responsible for founding Carnegie Mellon University, an educational institution located in Pittsburgh, in the United States.
Carnegie started working as a picker when he was a child. He became the richest man in the world.
Already on North American soil, he started working as a bobbin picker and thread spools in a cotton factory. At the company, Andrew Carnegie caught the eye of a coil manufacturer, who offered him a more advantageous job. Then he was a messenger for another company. His insight helped him to understand the city map and the faces of important people - and so he made several contacts. Little by little Andrew Carnegie grew in the company. In 1953, he left to work on a railroad. At 24, he was superintendent. At the post, he brought his younger brother and a cousin to work with him. In 1865, Andrew resigned to start his own company, the Carnegie Steel Company, which built Ohio's first steel bridge, and Union Iron Mills. Through the Carnegie Steel Company and applying the knowledge he acquired from Thomas Scott, his former boss, he invested in the steelmaking process. This dominated the metallurgical industry in the city of Pittsburgh.
