There were three tycoons on board the Titanic. There is no evidence that any of them opposed it; in fact one of them supported it. And no indication their presence would have made a difference.

J. P. Morgan, however, had to cancel his reservation on the ship, operated by one of his subsidiaries, and survived. He was a proponent of the Federal Reserve, having been part of the conference on Jekyll Island. The loss of the Titanic was a financial disaster for Morgan, but he set that aside in the face of the loss of life.
