"What sets this Hungarian school apart is its ability to sift the timeless from the timeworn. It does not cling to obsolete dogmas; rather, it rediscovers enduring truths too often overlooked by modern economics: that policy exists not for growth alone, but for prosperity that reaches real people."Viktor OrbánPrime Minister of HungaryA timely and thought-provoking book, The Middle-Class Revolution offers philosophical insights and practical policy guidelines to the greatest challenges faced by our societies: the shrinking middle classes, the growth of the wealth gap and increasing internal conflict. Drawing from the experience of Hungary between 2011 and 2021, the author presents how the Hungarian government's meritocratic social and economic policies extended the middle class by nearly 20 percent in just one decade — making the country the most successful in the European Union in rolling back poverty during this period.The book concludes by introducing one of the most comprehensive methods currently available for measuring sustainable development of wellbeing: the Harmonic Development Index. This exclusively data-driven index is unique in its ability to measure sustainability in all of its important aspects: economic, financial, environmental, work- and knowledge-based, social and demographic.Readers will surely find The Middle-Class Revolution a powerful roadmap for building more equitable, resilient and inclusive societies.
