To be 'surprised' at the results of concentration, to 'reproach' the government of capitalist Germany, or capitalist society ('ourselves'), to fear that the introduction of stocks and shares might 'hasten' concentration, as the German 'cartel specialist' Tschierschky fears the American trusts and 'prefers' the German cartels on the grounds that they do not, 'like the trusts, hasten technical economic progress to an excessive degree' is not this impotence?
