This statement is scarcely honest, for it quotes opinions of Adam Smith and others which are erroneous, as will be seen in the following, and which have been generally abandoned. This statement may impose upon the simple by its show of learning, but it is somewhat vague, for it only suggests, but does not distinctly assert, that manual labour is the only source of wealth. However, in most--one might say in nearly all--Socialist books, pamphlets, and declarations of policy we find the basic doctrine of Socialism asserted in a form which leaves no doubt that according to the Socialist theories the manual labour of the labourer is the only source of wealth. The founder of modern Socialism declared, "Labour is the only source of wealth,"[152] and his disciples--at least his British disciples--support that declaration. "All wealth is due to labour; therefore, to the labourers all wealth is due."[153] "Labour applied to natural objects is the source of all wealth."[154] The Socialist Party of Great Britain declares: "Wealth is natural material converted by labour-power to man's use, and as such is consequently produced by the working class alone."[155] The Independent Labour party asserts: "No man or class of men made the first kind of wealth, such as land, minerals, and water. Therefore no man or class of men should be allowed to call these things their own, or to prevent others from using them (except on certain conditions), as the landowners and mine-owners do now. The only class of human beings who make the second kind of wealth are the workers. Working men and women produce and prepare for us all those things which we use or consume, such as food, clothing, houses, furniture, instruments and implements, trams, railways, pictures, books, gas, drains, and many other things. They produce all the wealth obtained by toil from the land."[156]
