Yet, these regularly recurring catastrophes lead to their repetition on a higher scale, and finally to its violent overthrow. There are moments in the developed movement of capital which delay this movement other than by crises; such as e.g. the constant devaluation of a part of the existing capital: the transformation of a great part of capital into fixed capital which does not serve as agency of direct production; unproductive waste of a great portion of capital etc.
