At the outset of the twenty-first century, the situation of British Nationa
l Insurance is one of paradox. Due to socioeconomic changes and successive
government policies over the past three decades, the contributory principle
, which was a cornerstone of social security reconstruction after World War
II, has been in remarkable decline. At the same time contributions to the
National Insurance Fund increased significantly and continues to represent
a substantial form of total social security revenue. The contributory princ
iple has a broad public appeal, but National Insurance does not figure prom
inently in public debates and the system is poorly understood. Recent polic
ies have added to the ambiguity as to how far the contributory principle co
nfers social rights, and have further eroded its rationale. The article sta
tes that this situation is not matched by developments in other European co
untries. Despite substantial reforms and heated debates marked by controver
sy, the prospect for social insurance and the contributory principle appear
s considerably better than in the UK. One major explanation is, the article
argues, the distinctive notion of social insurance in Britain and particul
arly the lack of "wage-replacement" transfers. Elsewhere in Europe, earning
s-related transfers sustain a very different incentive structure, instituti
onal involvement and wider public participation in matters of social insura
nce.
