Governments and social partners in the European Union (EU) look for ways and means to adapt welfare systems to new needs, to keep expenditure under control, and to find alternative and supplementary financial resources in order to cope with future financial commitments. The EU is actively involved in the search for solutions to these common problems. It becomes more and more evident that only an active economic, budgetary, taxation and social policy mix can provide a solid base for safeguarding social systems. The author presents the most recent figures relating to actual and future social protection expenditure in the EU, disaggregated according to function and showing significant differences between gross and net figures. Attention is also paid to coverage and replacement rates of social benefits and to the availability of social infrastructures. The article then shows the shifts in implicit tax rates on labour in comparison with the rate on other factors. The conclusion outlines a European trade union view on the future of social protection in Europe and suggests possible issues for social benchmarking.
