Both Greece and Venezuela should default on all their bonds, rightly citing that they're all odious debts. 

Greece because they were manipulated by George Papandreou and Goldman Sachs (The Kraken) into the EU with a scheme that by some estimates now comprises thirty to forty percent of Greece's current debt. Debt that was substantially exacerbated by the fact that, according to some estimates, ninety five percent of all the additional loans given to Greece since the start of the crisis have gone directly to the EU's Banksters. Only five percent to the Greek government and practically none went to the Greek people. 

Although much of Venezuela's current economic difficulties were self-inflicted.  It didn't help that their government and their economy were under constant stealth attack by both the Banksters and wealthy, traitorous, Venezuelans. -- Deliberate economic sabotage has been ongoing for years. 

Both countries must disown their debts, establish free markets for the tangible portion of their economy, remove the Banksters, close their bond markets, and very importantly, issue a currency -- digital and paper -- that cannot be counterfeited and whose production is publicly known. 

Perhaps the digital signature for each note can be recorded and transmitted for each transaction.  If the production of the currency is known, along with accurate economic statistics, and the currency cannot be counterfeited or produced in excess of economic production, the currency will be stable. 

Once that's done, fiat (currency in excess of production or available collateral) should be banned.

Any foreign fiat (securities of any sort, stocks, bonds, etc, priced in the issuers currency, and the currency itself)  in excess of that entity's PPI and GDP that attempts to enter the country should be taxed by the amount of the excess plus a percentage of the amount of the tax. (the more excess fiat, the greater the tax) 

This may sound excessively oppressive and complicated from a free market prospective, but it actually would be much less oppressive and complicated than the current system of Banksterism....

• with its vast hidden Byzantine layers of ownership (the Fed for example, which is owned by a dozen or so foreign, Euro-Kazarian, families in Europe through interlocking directorships at hundreds of interlinked financial institutions)
• fiat produced as non-collateralized interest bearing debt notes (which mathematically can only end in an eventual economic implosion)
• rules and regulations of astounding, self-aggrandizing, complexity (all written by the financial industry)
• specialized, discriminatory, financial structures that yield unearned advantage to the select few, (primary bond dealers are just one example. There are hundreds of others)
• rating agencies that constantly and blatantly lie on behalf of their Bankster masters so their masters can gain further unearned geo-political and economic advantage (Moodys, Fitch & S&P)
• totally opaque "markets" (more than one quadrillion in unregulated, unknowable, and  therefore unpriceable derivatives for example)
• phony "markets" (its estimated that eighty percent of the trades on the New York Stock exchange are caused by high-frequency trading. Just electronic orders being placed, and most not even settled, by a bunch of computers)
• mark to fantasy, off-balance sheet accounting, re-hypothication, and all the other ways of producing leverage / fiat in excess of the "real".

Lets face it, there is no "price discovery" in the financial "markets" anymore.  In fact there haven't been any price discovery or "free markets" since the Banksters took them over and started producing fiat - at will - more than two hundred years ago. 

But of course now these "markets" have become an obvious and very expensive joke on the ninety nine percent of mankind currently laboring under complete fiat feudalism, and debt serfdom.

Such a hermetic national financial "shell" hopefully would act as membrane "of the real", automatically translating foreign "fiat", and stripping out its leverage, while converting it into a currency product backed by tangible real assets. A financial shell which would possibly eliminate the Banksters favorite methods of financial attack and infection.

Their constant and growing exponential use of unlimited fiat leverage to destroy currencies and their affiliated bond markets while gaining unearned advantage over a targeted society's economic resources and output. - mpg
