Australian economist Steve Keen (Sydney, 1953) has remained one of the few experts who warned of the past financial crisis before it arrived. Although his warnings were not heeded and the financial system collapsed. Now his latest work arrives in Spain, in which he asks ‘Can we avoid a new financial crisis?’ (Captain Swing). Keen, who responds to elDiario.es in a video call from Bangkok, argues that it is private debt bubbles that cause financial crises, while regulations focus on debt and public spending, especially in the European Union, with which is very critical, in addition to the euro. Defined as a Keynesian-Marxist, he is a firm defender of the participation of the State in the economy, without renouncing the market economy. Every time he has a chance, he opposes the thinking of orthodox economists, whose recipes continue to mark the agenda of the debate, despite the fact that they erred in the past economic crisis.
