What this portends is what i have been expecting. The advent of full financial disclosure. It will be the only way in which criminal enterprise itself can be stifled that does not harm anyone else. And by the way diverting a portion of a sales margin to a low tax jurisdiction is not properly a criminal or moral failing if fully disclosed, but sound business that needs to be accepted. That same money needs to be properly repatriated in order to be used and that typically incurs tax consequences.
Once disclosure kicks in, offshore dealing loses most advantage except in situations where ownership needs to be protected against rapacious litigation which is a nasty problem in the USA in particular. That by the way is the other side of this secrecy nonsense. There are predatory jurisdictions.
In the meantime, secret payments need to be disclosed or extracted by force in order to end this epidemic of global tax evasion. The forced resignation of the Prime Minister of Iceland fair or unfair is a good start. Public officials need to understand that secret payments will now be actively sought out and disclosed everywhere.
