“Until recently, very few people in the US and the UK were interested in debating these questions. Socialist movements were in deep retreat. The possibility of a world without capitalism seemed preposterous. In recent years, this possibility has started to look less preposterous. New leftwing momentum in both countries, propelled by popular upheavals and the campaigns of politicians such as Bernie Sanders and Jeremy Corbyn, has put socialist ideas back into circulation. Poll after poll demonstrates the rising popularity of the term. Forty per cent of Americans now say they would rather live in a socialist country than a capitalist one.“
