"Russian state capitalism has become the example for other nations as indicated in the rise of fascism and the growth of governmental control in all countries. However, this trend is no sign of ‘progress,’ as many people believe. It does not correspond to a ‘higher stage’ of capitalism, but indicates the decline of world capitalism. The trend toward bolshevization and fascization is only the political expression of the stagnation and decline of the capitalist system; it is barbarism."
