Nothing matches the self-righteousness of the bankrupt who reports a hard-working saver to a government which has just outlawed the ownership of useful money.  It was this kind of action against decent people which spawned a demand for constitutionally protected bank secrecy.  Power over banks is all too easily abused by governments to criminalise particular forms of property.  The wheel has now spun, and under the arguable case against money laundering banks in many western countries now act as information agents for the state.  It has advantages, but dangers too.
