Goldman Sachs chief attacks David Cameron on tax avoidance "This is an issue whose time has come," Mr Cameron said. After years of abuse, people across the planet are calling for more action and, most importantly, there is gathering political will to actually do something about it. Mr Blankfein also said that Britain's competitiveness and its attractions as a financial centre would be harmed if it were to leave the European Union. However, he did not believe that raising the issue in the way Mr Cameron had was in itself detrimental. Britain's strong legal system had helped to drive the country's success as an international financial centre, said Mr Blankfein, adding: "Can you sue in the commercial courts and get justice? Can you sue the sovereign and get fair treatment? Tax rates also helped the UK, he said, adding: "Having a 75pc marginal tax rate in France is not going to make people go there."
