From 22. to 24.2.2013, the second Solidarity Congress in Vienna will take place. The program includes a broad diversity of approaches for a world free from exploitation, inequality and unnecessary suffering. Notably, a special slot on demonetization will cover questions of how to transcend markets, money and exchange, replacing them with commons and solidarity economies. Congress language is German, but workshop descriptions are available also in English.
