A quick note - if the Greek Government introduced a Tax on The Use of Money, many of the current problems might be solved.
The tax would solve the problem of unpaid and uncollected tax revenue, at little extra cost.
The flow of financial information would alleviate the concerns of the lending banks.
The transparency of tax revenue would help plot the long term loan repayment schedules.
It is more than likely that the EU banks would view Greece as a much more secure investment and extend the loans.
