How Tycoons became rich?

The most important aspect of Carnegie's life is when he became the wealthiest in the 19 century. His aspect is important because he went from poor to rich. He did this by buying railroads and other company's that help him sell steel. Then when started becoming rich he donated to charities and became a American model of success.
A tycoon is a wealthy, powerful person in a business or industry. These people got rich by having a mind for business. They would look for a way to make products better and cheaper, so they would try to get rid of their competition through illegal means.
A strategie tycoons would use was to attempt to control as much of the business as possible through vertical integration.
Robber barons is when the business owners finish their vertical integration they would rise pieces of their product. Also they would reduce pay for all works.
Social Darwinism is when people thought being rich was a sign of god's favor and being poor was a sign of being lazy. Rich men like this social Darwinism philosophy because they saw it as survival of the fittest and natural selection.
