“Essentially the same land system as that of Ireland exists elsewhere, and, wherever it exists, distress of essentially the same kind is to be seen. And elsewhere, just as certainly as in Ireland, is the connection between the two that of cause and effect. 

….. Whence come the incomes which the owners of land in mining districts, in manufacturing districts, or in commercial districts, receive for the use of their land? Manifestly, they must come from the earnings of labor – there is no other source from which they can come. From what are the revenues of Trinity Church corporation drawn, if not from the earnings of labor? What is the source of the income of the Astors, if it is not the labor of laboring-men, women and children? When a man makes a fortune by the rise of real estate, as in New York and elsewhere many men have done within the past few months, what does it mean? It means that he may have fine clothes, costly food, a grand house luxuriously furnished, etc. Now these things are not the spontaneous fruits of the soil; neither do they fall from heaven, nor are they cast up by the sea. They are products of labor – can only be produced by labor. And hence, if men who do not labor for them, it must necessarily be at the expense of those who do labor.”

The Land Question: what it involves and how alone it may be settled”, Henry George, 1881
