In a democratic society, public policy must claim to provide what people want. One clue to this is the evidence of opinion surveys. Yet, in the field of welfare, surveys set policy analysts a puzzle: evidence about attitudes to what government should be providing displays an ambiguity. Some surveys demonstrate popular preferences for market provision, suppressed to a considerable extent by the coercive system of tax-financed state welfare, and others reveal a high level of satisfaction with and support for existing public welfare services. Both sets of opinions are tinged with a moralistic concern about the regulation of state services for stereotyped undeserving scroungers. The paper suggests that this ambivalence in findings is not simply the result of methodological difficulties: it may reflect an ambiguity in many people's attitudes in this area that is founded on the contrast between the ideology of individual self-interest prevalent in a market society and awareness of common needs for collective provision. Both aspects contribute to people's framework of ideas about the proper role of the state. Evidence from a recent survey is analysed to highlight the contradiction, and support this interpretation.
