Thomas Robertson's book "Human Ecology" is a critical analysis of the financial system and its devastating effects on society. Robertson argues that the financial system, based on debt and usury, has created an inverted social order in which the mechanisms of power are controlled by a financial oligarchy. The book examines the seven main mechanisms of society - finance, industry, sanctions, administration, politics, education and religion - demonstrating how each of them is manipulated by financial power. Robertson argues that this dependence on debt has led to increasing social instability, the destruction of individual freedom and the inability to solve the world's problems. The book concludes with a call for a new social order based on a free and decentralized monetary system, in which debt is no longer a constraint on human prosperity.
