For those quick to engage in "OMG" statements about the current state of the Greek economy, keep in mind the debt is an artificial number of compounded debt with exuberant interest added, and does not represent true expenses. The games played on the backs of Greeks by foreign 'investors' (speculators) can be summarized in the
Lehman Brothers bankruptcy aftermath. Billions were made by speculators that turned Greek debt papers into gambling fodder, thus sending the debt skyrocketing.
The Greek governments since 2008 have attempted to define a path to reversing this ballooning by imposing anti-social measures, restricting public employees, pensions and wages, and by increasing direct and indirect taxation to a point that it's not bearable any more.
Despite great advancement by the right wing / socialist coalition government, in January early elections were held due to an impasse in voting for the president of the Greek republic. So Greeks elected a leftist government this time, that consists of mostly old PASOK socialists - the very core that ruled Greece from the 80's and for 20 years - and the current stance of the Greek government asks for no more overseeing of the management of funds, and delivering a debt 'haircut'.
Unfortunately, Eurozone bankers (aka "banksters") continue to play a game that has an underlying political agenda; for example, Angela Merkel's seemingly hard stance is in fact friendlier than that of her own minister of finance; the political domino will expand in strong economies of the Eurozone, primarily Germany.
What needs to be done, is elimination of a large portion of this artificially ballooned debt, lowering of taxation for investments and the attraction of capital to rejuvenate the economy. Even if Greece unilaterally stopped payments, the switch to a new drachma currency would create issues with inflation temporarily; the market would then become even more competitive as a tourist destination. However, that does not solve the issue long term, as manufacturing production needs to be increased and modernized. Greece is looking into investments from Russia (gas pipeline co-oped with Turkey and Bulgaria) and China (shipping sector).
One needs to understand that Greeks are not alone in how they perceive this financial slavery to banks and hedge funds; Spain, Portugal, Italy and even France are facing similar issues.
