The danger of the co-existence and collaboration of the two economic systems –the capitalist and the socialist–lies in the fact that the capitalist forces may get the best. The argument concerning the danger of war or blockade in the event of our " growth into the world market " is too thread-bare and abstract. The only dangers that would then have threatened would have been political, or a military break through our " self-sufficient " system from without. If we had intended to remain to the last economically a " selfsufficient " country, the problem, in essence, might have been considered as solved. If in economic questions the Government is not all-powerful, at least the economic forces of the State when the latter consciously fosters the progressive tendency of historic development become enormous. On Soviet territory, socialist economics are struggling with capitalist economics, the former supported by the workers' State.
