For Karl Marx, the concept of political freedom is rooted in an essentially collectivist notion of economic freedom. Most importantly, he considered all freedom to be based on freedom from economic necessity. In other words, if you are living in poverty in Sudan, you cannot enjoy any form of political freedom, whatever the putative nature of your society's political system, because all your energies must be devoted to simple survival. Thus for Marx, the start of freedom is too make sure people have adequate food and shelter. Next, he thinks of freedom as much on a class level as an individual one, i.e. that the freedom of workers to control the conditions of their work is not just about Ahmed or Jill or Jose getting a better deal from a boss, but about all people in an oppressed economic class being able to rectify oppressive systems.
