This question refers to the text "Capitalism Will Eat Democracy — Unless We Speak Up." In it, Yanis Varoufakis talks about the importance of democracy and the dangers that uncontrolled capitalism poses to it.
In the text, Varoufakis argues that, unless we take control of capitalism, the future could be a dystopia in which economic concerns are the only important ones and democracy has disappeared. Instead, the utopia that he suggests is one in which we demand democracy, and a democracy that includes all individuals. He suggests we achieve this by speaking up and demanding that democracy is protected. If we fail, we risk losing democracy altogether and being controlled completely by the fluctuations of the market.
