Keynes supported free markets but as long as these were regulated by state intervention in order to soften the peaks and troughs in the business cycle.

Smith was an advocate of free markets and of supressing state interventionism. On the other hand, Marx was in favour of massive intervention of the state because he considered markets to produce un unfair distribution of wealth in the states, where the richer ones exploited the poor.
