Support for the point I was making in my column yesterday:
Rethinking Parameters of the US Welfare State, by Tim Taylor: ...The ... question ... was about whether the welfare state undermines productivity and growth. Garfinkel and Smeeding point out that in the big picture, all the high-income and high-productivity nations of the world have large welfare states; indeed, one can argue that growth rates for many high-income nations were higher in the mid- and late 20th century, when the welfare state was comparatively larger, than back in the 19th century when the welfare state was smaller. Indeed, improved levels of education and health are widely recognized as important components of improved productivity. As they write: "Furthermore, by reducing economic insecurity, social insurance and safety nets make people more willing to take economic risks."
One can make any number of arguments for improving the design of the various aspects of the welfare state, or to point to certain countries where aspects of the welfare state became overbearing or dysfunctional. But from a big-picture viewpoint, it's hard to make the case that a large welfare state has been a drag on growth. Garfinkel and Smeeding write:"Of course, many other factors besides social welfare spending have changed in the past 150 years. But, as we have seen, welfare state spending is now very large relative to the total production of goods and services in all advanced industrialized nations. If such spending had large adverse effects, it is doubtful that growth rates would have been so large in the last 30 years. The crude historical relationship suggests, at a minimum, no great ill effects and, more likely, a positive effect. The burden of proof clearly lies on the side of those who claim that welfare state programs are strangling productivity and growth. If they are right, they need to explain not only why all rich nations have large welfare states, but more importantly why growth rates have grown in most rich nations as their welfare states have grown larger."
