Andrew Carnegie is one of the biggest robber barons of the gilded ages.
For instance, he spent $10,000,000 to renovate his castle, which he didn't even live in full time. He took occasional visits there. Today, that would be $237,000,000. Carnegie could have used all this money to pay his workers better or to enhance his business.
Carnegie paid his workers less than the average daily wages for iron and steel workers. He paid them on average, $1.40 a day, when the average was $1.81.
$600 a year was what supported a typical 6 member family. With Carnegie's pay, they only made $511 a year. Many people who worked for him then could not support their family financially.
Carnegie also excessively controlled nearly all of the Messabi iron fields. He also owned the entire port facility and 6 ore boats. If he has all this money to own and control all of the things he does, he should use some of his money to better the working conditions of these facilities.
His Homestead iron mills had very unsafe working conditions. There was even a place in the facility which was nicknamed "The Deathtrap" because every so often, a man gets killed because of a broken chain or or fallen ladder.
Even though Walton's family has over $100 billion, he tried to avoid paying his workers even minimum wage.
Now, the average employee gets paid $8.23 an hour, which is not enough to be financially stable.
The Labor Department investigated Walton for his illegal practice of using a "small business" exception to the minimum wage. When the Labor Department ruled against him, he sued in federal court to keep paying his workers below the minimum wage, he lost.
