Is the era of globalisation, unfettered markets and billionaire philanthropists drawing to a close? Is the answer to rising populism for the state to tax the wealthy and invest more in the public good?

Manuela Saragosa speaks to three people who say the populist revolts, from Brazil to the US, are symptomatic of an economic system in crisis. Winnie Byanyima, head of anti-poverty campaigners Oxfam, explains why she thinks global jobs statistics mask the reality that many people do not receive dignified work or a decent wage.

Development economist Paul Collier of Oxford University says he thinks corporations and billionaires have lost their way in an era of shareholder value and a growing wealth gap, while journalist Anand Giridharadas claims we are witnessing the death throes of the free market ideology that has dominated global politics since the 1980s.
