One of the few people in the world who has a well-informed insider’s perspective who is also happy to speak out about it is Brooke Harrington of Copenhagen Business School, who took the remarkable step of actually obtaining a professional qualification in wealth management to pursue her studies. As she told our Taxcast recently:

“Tax avoidance was really only the tip of the iceberg. I didn’t realise how much bigger the problem is. Really what wealth managers do extend much more generally to law avoidance. And that creates problems of legitimacy for whole governments: it’s bad enough that people think they are getting shafted because the rich aren’t paying their fair share of taxes: it’s quite another matter when you say there is one law for the rich and one for everyone else and they are not the same: that is the sort of thing that can potentially topple governments.”
