International Workers’ Day, May 1, represents more than a celebration of past gains such as higher wages, improved benefits, better working conditions, and shorter hours. IWD signifies the class struggle to abolish capitalism and to establish a system free of exploitation and oppression. Only by socialist revolution can the immense majority of humanity create the basis for freedom from want, for a bottom-up economic and political democracy, for a world cleansed of national and gender-based tyranny. It is the only way to save nature and humanity from the growing threat of extinction caused by a system dominated by carbon energy profiteers and their servants in state power.
