James S. Henry introduces a hot topic: offshore banking. The G8 and G20 are planning meetings to discuss it. Even the Netherlands is a tax haven for certain types of companies. The huge amount of numbers and graphs tells us that we are confronted with nothing less than a global tax haven industry. For example, Apple makes 100 billion dollars a year of tax free profits because of the games private bankers know how to play.

In medieval times people couldn't hide their wealth when tax collectors came to inventory it. Nowadays they can. It is said that 64 percent of the global profits are parked offshore, for an important part by multinationals from the first world.

The third world is the victim of this practise. An example from the banana industry: exporting a banana from the Cayman Islands costs 13 pence. When it arrives in the UK to be consumed, the costs have grown to 60 pence. All of this money goes to other parties than the Cayman Islands.

Because of the tax havens, countries from the Third World are not able to receive the tax incomes they are entitled to. Henry even concludes that the debt problem of the third world is not a debt problem, but a tax problem. Both amount to almost the same.
