 Quite apart from matters of efficacy, there are moral questions about the state promotion of happiness, which has been a major subject of debate, both because of the literature on mistakes and research suggesting that the traditional focus of state efforts to promote well-being, economic growth, has a surprisingly modest impact on  happiness.  One concern is paternalism: does happiness-based policy infringe too much on personal liberty? Some fear a politics that may too closely approximate Huxley’s Brave New World, where the state ensures a drug-induced happiness for all (Huxley 1932 [2005]). Extant policy suggestions, however, have been more modest. Efforts to steer choice, for instance in favor of retirement savings, may be paternalistic, but advocates argue that such policies can be sufficiently light-handed that no one should object to them, in some cases even going so far as to deem it “libertarian paternalism” (Thaler and Sunstein  2008).[35]  The idea is that gentle “nudges,” like setting default options on hiring forms to setting aside money for retirement, interfere only trivially with choice, imposing little or no cost for those who wish to choose differently, and would very likely be welcomed by most of those targeted.
