Este trabajo es uno de los frutos empíricos del proyecto de investigación Reformas en el Estado de Bienestar: Actores y Apoyos Ciudadanos (REBAAC), http://www.iesam.csic.es/proyecto/rebaac.htm, dirigido por Luis Moreno, que se completará en los próximos meses con otros escritos sobre el tema.In recent years pressures for the reform of the Welfare State have been voiced despite that public opinion has kept opposed to the retrenchment of social policies. Some studies have pointed out that governments have learned how to avoid popular resistance to the reforms due to a change in citizens’ attitudes. This Working Paper explores the attitudes of the Spaniards with respect to the process and outcomes of the welfare policies implemented in Spain in the last 20 years. Whenever possible this paper takes a comparative. Time series have been worked out covering the period under analysis. Likewise, preferences towards the various welfare policies and these and other public policies are also compared. The two main conclusions are that the support for the welfare policies is solid (despite some qualifications) and that the public preference for the meso or intermediate level of government as provider of social policies has increased.
