“As soon as the land of any country has all become private property, the landlords, like all other men, love to reap where they never sowed and demand a rent even for its natural produce. The wood of the forest, the grass of the field, and all the natural fruits of the earth, which, when land was in common, cost the labourer only the trouble of gathering them, come, even to him, to have an additional price fixed upon them. He must then pay for the licence to gather them, and must give up to the landlord a portion of what his labour either collects or produces. This portion, or, what comes to the same thing, the price of this portion, constitutes the rent of land, and in the price of the greater part of commodities, makes a third ” - Adam Smith

"The interest of the landlord is always opposed to the interests of every other class in the community. His situation is never so prosperous, as when food is scarce and dear: whereas, all other persons are greatly benefited by procuring food cheap." - David Ricardo

“And this is the economic constitution of our entire modern society: the working class alone produces all values. For value is only another expression for labour, that expression, namely, by which is designated, in our capitalist society of today, the amount of socially necessary labour embodied in a particular commodity. But, these values produced by the workers do not belong to the workers. They belong to the owners of the raw materials, machines, tools, and money, which enable them to buy the labour-power of the working class. Hence, the working class gets back only a part of the entire mass of products produced by it. And, as we have just seen, the other portion, which the capitalist class retains, and which it has to share, at most, only with the landlord class, is increasing with every new discovery and invention, while the share which falls to the working class (per capita) rises but little and very slowly, or not at all, and under certain conditions it may even fall.” - Karl Marx

“The businessman is only tolerable so long as his gains can be held to bear some relation to what, roughly and in some sense, his activities have contributed to society.” - John Maynard Keynes
