Adam Smith on Welfare State - Dictionary of Arguments
Mause I 153
Welfare State/Adam Smith: That the price on the market is welfare maximizing is the subject of the famous theorem of the invisible hand by Adam Smith (1723-1790). If all market participants behave selfishly (rationally), according to Smith the market coordinates the individual partial interests towards the welfare maximum. For the economic driving force here is not the "goodwill of the butcher, brewer and baker" (Smith  1978, (1)), but the respective self-interest of the market participants.
Invisible Hand/Smith: The individual concerns of each one are guided across the market "by an invisible hand to promote a purpose which he has no intention whatsoever to fulfil". (2)
