Absolutely. Morally they're probably all guilty of something but legally I bet it's all 'above board', same with big companies avoiding tax. Not sure what you do with all that money anyway after you've bought your first yacht i.e. Why not pay some tax?! Or do something like Drogba did building...
None of them are guilty, it's probably the ridiculously complicated tax laws that's the common themes here. expect deals to be done but no ones going to jail that's for sure.
