Greek officials said Monday that there is no way that they could come up with the money required to meet the country’s debt payment of 1.6 billion euros ($1.7 billion) due Tuesday to the International Monetary Fund.

Five years of Greece’s economic troubles and the grueling austerity that resulted have sawed away at its middle class.

“This is an invisible war,” Stalo Mestana told The Washington Post.  “It’s like an emotional, economic war.” She said.

It’s also a “war” documented by the graffiti painted on buildings across the country.

“Graffiti in Athens used to be all about football, politics or teenage crushes,” the Associated Press recently wrote, “silly enough to be laughed off, rare enough to be frowned upon.” But as the country burrowed deeper into financial distress, Greek graffiti has shifted focus. Wheatpaste posters and murals show anger, frustration and political awareness.

“The middle class and the working class in Greece have been ruined,” Mapet, a Greek dentist turned street artist told the New York Times last year. “My goal is to deliver social and political counterpropaganda, and make people think.”

“If you want to learn about a city, look at its walls,” Greek street artist iNO, told the Times last year. “Take a walk in the center of Athens, and you will get it.”
