 However, Johan Norberg of CIS, a free enterprise economy think tank, presents a hypothesis that as people who think that they themselves control their lives are more happy, paternalist institutions may decrease happiness.An alternative perspective focuses on the role of the welfare state as an institution that improves quality of life not only by increasing the extent to which basic human needs are met, but also by promoting greater control of one's life by limiting the degree to which individuals find themselves at the mercy of impersonal market forces that are indifferent to the fate of individuals.This is the argument suggested by the U.S. political scientist Benjamin Radcliff, who has presented a series of papers in peer reviewed scholarly journals demonstrating that a more generous welfare state contributes to higher levels of life satisfaction, and does so to rich and poor alike.
