István Mészáros wrote already about the structural crisis of capital in the early 1970s with a strong ecological critique. The capital system, points out Mészáros, is not a mechanism that can be logically controlled. On the contrary, the logic of capital overwrites everything, including heath care, education, production and the ecology. The drive for eternal accumulation undermines the conditions of existence. The logic of capital contradicts the ecological approach but a socialist society will be built on social and ecological sustainability.
