In the January 2018 Taxcast we explore the results of the Tax Justice Network's Financial Secrecy Index just out, that tell the real story of global corruption. We look at the top ten worst global offenders, discuss the 4 key geographical political poles: the Far East, Europe, Britain plus its cluster of satellite tax havens, and the United States. And we discuss what countries can do independently and as regional blocs to defend themselves against the threats to their economies from offshore secrecy jurisdictions.
