Well, Barbados has a thriving financial industry that collects millions of dollars in fees. From my experience in working in Barbados at the University of the West Indies, it's a very sophisticated tax-advising group. That's their livelihood. It's roughly 15% of their GDP, the financial industry, and it's a very important part of their economy.
It's the same with respect to certain other countries. Of course, the biggest tax haven by far in the world—a half to one-third of the world's tax haven moneys—is Switzerland alone, but important other players exist in the Caribbean, the Isle of Man, and in other places, of course, throughout the world. They make a lot of money off this.
