The point of departure for this paper is US evidence claiming that citizens do not possess an adequate understanding of the concept of progressive taxation. Using the format of standard survey questions, most respondents preferred progressive taxes. When faced with similar questions framed in concrete terms, a majority rejected progressive taxes. By analysing data from Sweden, it is shown that irrespective of whether abstract or concrete measures are applied, most citizens support progressive taxation. There is no evidence indicating that Swedes in general do not understand the concept of progressive taxation. To explain why US citizens are more ignorant about progressive taxation than Swedish citizens, it is suggested that the Swedish welfare state institutions and the surrounding political environment may be exercising a substantially stronger educational influence on the meaning of redistributive concepts.
