More than half of young people in Greece are unemployed, the worst record for any eurozone country. Many feel abandoned by the state and are frustrated and angry.
Emilio Papas opens the tall iron door to his squat near Exarhia Square, in the centre of Athens, to reveal an enormous five-storey building with high ceilings and a grand staircase.
"It was a health hazard for the whole community, full of dead birds, rancid water and maggots," he says about the abandoned social security office, which he now calls home.
In the past few months the number of jobless in Greece has shot up. The current total for young people stands at 51.1%, and Emilio Papas is one of them.
He smiles as he admits that the irony of the situation has not escaped him: living in a former social security office when neither he nor any of the other squatters has ever made any national insurance payments.
Last year Mr Papas and a group of his unemployed friends, aged between 18 and 32 years old, spent several months making the building habitable.
Each of the squatters has his own flat and they are planning on using the ground floor as a community centre for the neighbourhood.
They have also opened their doors to an older resident, 60-year-old George Koutselas, who would otherwise have been left homeless.
"I worked most of my life but none of my bosses ever paid national insurance contributions for me, so now I don't get a pension or any benefits.
"As far as the Greek state is concerned I don't exist," says Mr Koutselas.
Unemployment benefit in Greece is available only to people who have made national insurance contributions and since many young people have never had a job, they are not entitled to any financial support.
Even those who do receive the monthly payments of 360 euros (£300) see them stop after one year.
After that, unemployed people in Greece are on their own, without access to financial support or free healthcare.
