In an online book published by the Institute of Economic Affairs, Nima Sanandaji argues not only that the Scandinavian success story predates the welfare state but also that the welfare state actually undermined the success story. From the book’s summary:
Many analyses of Scandinavian countries conflate correlation with causality. It is very clear that many of the desirable features of Scandinavian societies, such as low income inequality, low levels of poverty and high levels of economic growth, predated the development of the welfare state. It is equally clear that high levels of trust also predated the era of
high government spending and taxation. All these indicators began to deteriorate after the expansion of the Scandinavian welfare states and the increase in taxes necessary to fund it.
