One of the things that is interesting about reading conspiracy theory is that much of what folks think is conspiracy is really many people acting in concert to make or protect their money. ― Catherine Austin Fitts
Lucy Komisar shed light a decade or so back on the offshoring
The Criminal Services Industry
Excerpt
While tax dodges are probably as old as taxes themselves, modern offshore tax havens date from the 1920s and 30s when Bermuda and Liechtenstein passed laws for offshore companies and trusts. After World War 1, many European countries raised taxes to rebuild their shattered countries and money soon flowed into low-tax countries like Switzerland which had suffered no war damage. Many countries eventually found the advantages of low taxes in attracting money or businesses to their banks. Secrecy laws also helped especially in small countries which found that the fees for such services could prop up their economies.
Today, England, the US and some European countries are replacing the more exotic Caribbean or Indian Ocean Islands as the tax havens of choice. On the Tax Secrecy index, the US state of Delaware is listed as the No. 1 offender by the Tax Justice Network. Delaware earns $700 million per year in company registration fees, a significant part of its budget.
