On the other hand, Greece imports energy, food, medicine and technology and those things will all have to be paid for with hard cash. The result of a 50% devaluation of the new Drachma will be a doubling in prices for basic life necessities.
It's clear to me that Syriza's policies have been and will be absolutely disastrous for the ordinary Greek person. Things may have been bad last year but at least there was a small uptick in GDP and employment and seemingly a small improvement in government finances. With a busted bank system, capital controls and no cash to pay for essential imports, I can see Syriza turning Greece into a fully failed state.
Some of those things, particularly medicine & food, are artificially high priced because you are in the EU:

I grant it will be difficult for a year or two, but I predict you will be better off in the long run.
Greece is the most enticing tourist destination in the world. It has everything .. history, culture, beaches, food etc. A devalued Drachma would draw an increasing portion of an industry that is poised for dramatic growth as more Indians & Chinese become rich enough to catch the tourist bug.
It's world-class shipping industry would also become more competitive against Korea, Scandinavia and Japan.
Syriza is not as "far left" as portrayed, and they are not as corrupt as previous Greek governments. Their finance minister, though he has described himself as a "libertarian marxist", has received strong praise from free-market institutions for various proposals.

The big problem for establishment magazines like the Economist has become, is that he dares to think for himself.
