 Refugees to a collective were also a problem, as existing members sometimes regarded themselves as more in tune with the collectivist spirit and felt that the refugees were a burden, at times reacting with hostility to independent efforts by newer members, while the refugees thought they were victims of discrimination.Tensions could also erupt between workers and those in charge of managing output, as well as disputes over how much work members were required to put towards the collective.According to historian Stanley Payne, the social effects of the revolution were less drastic than the economic ones; while there were some social changes in larger urban areas (Barcelona emphasised a "proletarian style" and Catalonia set up inexpensive abortion facilities), the attitudes of the lower classes remained fairly conservative and there was comparatively little emulation of Russian-style "revolutionary morality".
