This book is a companion to my book The Theoretical Solution to the British/Irish Problem, which gives a suggested constitution for the Federal Kingdom of Ireland and it recognizes a right, center, and left political structure of the Federation. The left structure is the Irish Christian Social and Democratic Party. Christian Socialism is peaceful in its origins and present form and is opposed to the violence of Marxist class conflict. In place of class struggle, Christian Socialism places class togetherness. Christian Socialism envisages a New Ireland and a New Ireland needs a new economic theory of the left. Georgeist economics fits the bill. George argued that land shouldn't be owned by individuals but collectively by the people. He held that there should be only a single land tax raised to meet the expenses of the state. This was a popular economic theory in the nineteenth century but was crushed by neoclassical economists such as Marx in the interests of the landed gentry in Ireland and England. Marx condemned the excesses of capitalists in their exploitation of labor but was silent when it came to the exploitation of tenant farmers in Ireland by the landed gentry. Georgeist economics need to be looked at again in twenty-first century Ireland.
