The author shows that although Shelley is taken as a “leftist”, the poet is not an enemy of capitalism, but of feudalism and mercantilism. Shelley advocated the abolition of government intervention in economy, and the implementation of free market to increase the welfare of England, reducing the gap between rich and poor. In addition, Shelley criticized the mercantilist government’s manipulation of the currency and the British national debt, as well as he supported full rights to property and inheritance. The author concludes that Shelley was much more a liberal than a socialist or proto-socialist.
