Tax dodging by big corporations deprives governments of billions of dollars. This drives rapidly increasing inequality. Recent G20 and OECD moves to clamp down on corporate tax dodging are a first step, but these have woken up a legion of opponents set on undermining them. Most developing countries, which lose billions to corporate tax dodging annually, are also being left out of the decision making. Commercial interests must not be allowed to pursue their agenda at the cost of the public interest. All developing countries must be included in negotiations, and corporations must pay what they owe.
