 The extensive production industrialization that resulted was not responsive to consumer needs and caused a neglect in the service sector, unprecedented rapid urbanization, acute urban overcrowding, chronic shortages, and massive recruitment of women into mostly menial and/or low-paid occupations.The consequent strains resulted in the widespread used of coercion, repression, show trials, purges, and intimidation.By 1960, massive urbanisation occurred in Poland (48% urban) and Bulgaria (38%), which increased employment for peasants, but also caused illiteracy to skyrocket when children left school for work.
