This document summarizes the opening address given at a global economic conference held by Hizb ut-Tahrir in Khartoum, Sudan in 2009. The address critiques the failed responses to the global financial crisis by capitalist nations and economists. It argues they only addressed surface-level symptoms and not the underlying flaws of capitalism. The address also argues mainstream economists ignore the viable alternative of Islam's economic system, which provided economic prosperity and security for centuries without crises. The opening call was for examining the real causes of periodic crises under capitalism and considering the superior system of Islamic economics.
