Banker J.P. Morgan is a self-made billionaire who buys out broken or failing industries and turns them to profit. Rockefeller also invests into iron which threatens Carnegie to hand over large amount of money to come to an agreement on terms that Rockefeller would back down.
Carnegie questions his future since he had battled with Rockefeller for over 30 years. Carnegie offers J.P. Morgan his company for 480 million, which is an estimated 310 billion dollars today and accepts the offer.
