Che Guevara
In Guevara's private writings from this time (since released), he displays his growing criticism of the Soviet political economy, believing that the Soviets had "forgotten Marx". This led Guevara to denounce a range of Soviet practices including what he saw as their attempt to "air-brush the inherent violence of class struggle integral to the transition from capitalism to socialism", their "dangerous" policy of peaceful co-existence with the United States, their failure to push for a "change in consciousness" towards the idea of work, and their attempt to "liberalize" the socialist economy. Guevara wanted the complete elimination of money, interest, commodity production, the market economy, and "mercantile relationships": all conditions that the Soviets argued would only disappear when world communism was achieved. Disagreeing with this incrementalist approach, Guevara criticized the "Soviet Manual of Political Economy", correctly predicting that if USSR did not abolish the law of value (as Guevara desired), it would eventually return to capitalism.
Tarará
After the Cuban Revolution, in January 1959, Che Guevara went to live at a summer villa in Tarara to recover from a violent asthma attack. While there he started the Tarara Group, a group that debated and formed the new plans for Cuba's social, political, and economic development. In addition, Che began to write his book Guerrilla Warfare while resting at Tarara. Che returned to Tarara in June 1959 for his honeymoon after his marriage to his second wife Aleida March.
