"The mass of workers, as yet non-Socialist, is retarded in its development towards Socialism"

In this quote, Karl Radek highlights the gap in between the potential and actual political consciousness of the working class in relation to the ideals of socialism. Radek's assertion that the "mass of employees, as yet non-Socialist, is slowed down in its advancement towards Socialism" suggests that despite the conditions being ripe for a socialist improvement, there is a delay or limitation in the employees' development towards embracing socialist ideology.

Radek's usage of the term "retarded" refers not to an intrinsic shortage in the employees but rather to external or systemic barriers that slow their ideological awakening. These barriers could consist of overbearing political systems, absence of access to education, adjustment by capitalist propaganda, or cultural customs that enhance the status quo. The idea is that the fundamental conditions under a capitalist system tend to obscure the awareness of the working class, distracting or pacifying them with incorrect narratives about success within the capitalist structure.

Moreover, Radek suggests that the working class has an untapped potential for socialism-- a natural alignment with socialist principles-- because socialism naturally seeks to attend to the inequities and exploitation that workers deal with under commercialism. Nevertheless, their motion towards socialism is not automatic; it needs a driver or a shift in circumstances that would awaken their class awareness.

The quote might likewise be an implicit critique of socialist motions or celebrations that have stopped working to effectively engage or mobilize the working class. It suggests a requirement for a more concerted effort in political education and organization, cultivating environments where employees can critically assess their conditions and see the viability of socialist solutions.

Radek's message underscores a sense of urgency: for socialism to accomplish its goals, it is vital to conquer the barriers postponing employees' accept of its ideology. Through education, company, and agitation, the socialist movement needs to strive to accelerate the development of class awareness essential for systemic modification.
