Overall, Greece lost 25% of its GDP during the crisis. Although the government debt increased only 6% between 2009 and 2017 (from €300 bn to €318 bn) — thanks, in part, to the 2012 debt restructuring —, the critical debt-to-GDP ratio shot up from 127% to 179% mostly due to the severe GDP drop during the handling of the crisis. In all, the Greek economy suffered the longest recession of any advanced capitalist economy to date, overtaking the US Great Depression. As such, the crisis hit hardly the populace as the series of sudden reforms and austerity measures led to impoverishment and loss of income and property, as well as a small-scale humanitarian crisis. Unemployment shot up from 8% in 2008 to 27% in 2013 and remained at 22% in 2017. As a result of the crisis, Greek political system has been upended, social exclusion increased, and hundreds of thousands of well-educated Greeks left the country.
