Dr Alf is not wrong. Large numbers of public sector workers, who until recently used to retire at 38 on a full pension only to take other jobs, will indeed be at risk.
Greece has probably already run out of money and is living off the residue of monies lent to it in the past(none of the publicly available figures can be believed because Goldman Sachs created wholly bogus data to enable Greece to enter the Eurozone in the first place and may either alone or via others be doing so now to create the impression that things are not as bad as they seem).
Before I lent Greece any more money, I would want to go through that country’s finances with an electron microscope and the forensic accountancy skills of someone like Dr Alf and his nephew, Seymour Lightman, an accomplished forensic accountant in his own right.
Greece does have assets but which ones it owns outright and which ones are unencumbered is a separate and as yet unanswered question.
Money has been spirited out of Greece by five of its leading plutocratic families and by others. The disposition of that money needs to be established and where possible monies that should be repatriated to Greece, should be along with the pursuit of justice and recompense against those guilty of criminality, malfeasance and subsequent money laundering.
