It is interesting that the quotations of impending doom come from importers who see no future. Stipulating that business is facing huge problems, why do they not attempt to source from domestic sources.
I suspect that trying to set up manufacturing in Greece is as futile as trying to do so in California. Any attempt results in swarms of bureaucrats and inspectors descending on you, fining you for infractions (and demanding payoffs).
The only way out for Greece involves eliminating 75% of government employees, and terminating much of the welfare state. Doing so will result in riots.
It's like being a drug addict: it's easier to try to get one more fix, than to contemplate the pain of going through withdrawal.
Quote No 1:
"Greece imports 40 percent of the food it consumes, nearly all of its oil and natural gas and much of its medicine"
Quote No 2:
"But, barring tourism, it does not have businesses or industries that could drive such a recovery"
Quote No 3:
""Greece would have a hard time to import oil, foods, medicines and other primary inputs. Imagine the navy, police, without fuel. Natural gas spigots would close"
Include software, computers, raw materials etc....spare parts for existing factories.
