THE BP disaster in the Gulf of Mexico is highlighting many things.

It shows the world we have to find cleaner fuels but it also shows us how free the multinational companies are.

Milton Friedman, financial adviser to Ronald Reagan and Margaret Thatcher, sought to free big business from controls. Multinational companies have grown strong and ruthless since then.

The populations and authorities are just beginning to see what this means.

BP is the tip of an iceberg that now runs very deep.

This disaster is a wake-up call to find ways to control these businesses.
