I work with a number of self employed people who have next to no idea how their money is managed or tax paid. People rely on experts/advisors for this sort of thing the moment money becomes any harder than earning a 'normal' wage and not having to do tax returns (although I am more than aware that many do look after their own tax returns). I doubt there are many high earners, regardless of their profession, who have asked their accountants to ensure that their finances are handled both legally AND morally.
I suspect there are a number of newspaper, TV and radio people reporting this with slightly squeaky bottoms in case their own finances were ever made public.
