It doesn't matter. If you think Tesla was the big loser who was somehow "destroyed" by JP Morgan, the fact remains that the age of the great industrialists was way back then. The claim was that today is the period of the great American industrial empires. To anybody with any idea of American history, that idea is preposterous. Today's companies are primarily owned by millions of grandma's via their 401K.
I happen to disagree with the assertion that Tesla was destroyed - we both know his name, despite the fact that he was more talk than action.
