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.

In Chile, Guevara found himself enraged by the working conditions of the miners in Anaconda's Chuquicamata copper mine and moved by his overnight encounter in the Atacama Desert with a persecuted communist couple who did not even own a blanket, describing them as "the shivering flesh-and-blood victims of capitalist exploitation". Additionally, on the way to Machu Picchu high in the Andes, he was struck by the crushing poverty of the remote rural areas, where peasant farmers worked small plots of land owned by wealthy landlords. Later on his journey, Guevara was especially impressed by the camaraderie among those living in a leper colony, stating, "The highest forms of human solidarity and loyalty arise among such lonely and desperate people." Guevara used notes taken during this trip to write an account, titled "The Motorcycle Diaries", which later became a "New York Times" best-seller, and was adapted into a 2004 award-winning film of the same name.
