All organized crime organizations eventually depend on violence or fall victim to it.
Usually the threat of violence is enough to persuade white collar targets to cooperate.
And yes, I can cite a number of white collar crimes that are being perpetrated with the majority of proceeds going to organized crime organizations. But giving you details is not going to happen.
White collar crime is one of the most attractive forms of crime for career criminals. It provides a very high reward:risk ratio. The bulk of the risk is assumed by the inside contact, who is not part of the crime organization. The inside contact is in a pickle; he cannot contact the authorities, because not only is he guilty of the white collar crime, but he would be putting himself and his family in danger of being a target of violence from his criminal associates. If you see a high level business executive commit suicide, there is a good chance he got in over his head.
But do not take my word for it. This is from your very own FBI:
