Andrew Carnegie used the lower wages to fix his image to the rich public by using the extra money to give donations and build mega-structures for other wealth people.
While Carnegie was making $92,000 a day while his men made just $1.81 in that same day. The payment he was giving could not support a common family of 6 with that payment. Those families needed at least $600 a year to survive. Carnegie should have treated his workers better than that making all the money that he did.
Andrew Carnegie was a class A Robber Baron with a hunger for wealth at no cost to him.
Now in this day and age the money making robber baron is Apple.
