Collective Choice and Social Welfare, attempted to rescue welfare economics from the pessimism of free-marketeers, who argued that there was no point in government intervention, and that individuals should be left to choose whatever the market made available in response to their choices, and statists, who concluded that authoritarian choices had to be made by governments on other people's behalf. Sen argued that perfection in social decision-mak ing is unnecessary. Partial comparisons between people can help and majority decisions do carry weight, as long as the interests of the less assertive citizens are not ignored.
