Abstract economic theories are greatly responsible for the massive crisis that began in 2008 and for its recent predecessors. In particular, the mathematical compounding of interest on borrowed capital has proven to be unsustainable in the real world, as it contravenes the laws of thermodynamics and leads to bubbles spurred by aggressive deregulation. The world must reorganise economic systems according to multidisciplinary data that take “externalities” into account. High frequency trading and currency speculation should be drastically curbed through taxes and legislation and, in the US in particular currency emission reclaimed from private banks. In such a “real” economy, sustainable “green” technologies may be properly funded and promoted to create employment and solve environmental problems.
