Greek Dimitris Pikrodimitris reacts while talking to reporters in Athens in this July 4 photo. Pikrodimitris took out a mortgage four years ago when he was drawing an annual income of 27,000 euros (US$36,720). But the economy quickly sank into a debt crisis, forcing Greeks to tighten their belts and driving the insurance agent’s wages down to just 6,500 euros last year. The number of defaulting debtors like Pikrodimitris is growing in Greece, and experts are warning that the situation could blow up and smash hopes the country can finally emerge from a crippling six-year recession this year. Greece’s central bank said that nonperforming loans — loans for which debtors have failed to make payments for more than 90 days — are currently worth 77 billion euros. SD-Agencies
