Let's contextualise properly. The program was called How the Rich Beat the Taxman - the example given was of how a rich person (George Osbrone) beat the taxman and avoids paying tax. Your 6 apparent points are in fact, one - lots of people do it. Are they all the Chancellor i wonder?
On tax evasion, George Osborne has just signed a deal with the Swiss that practically says go ahead, tax avoid, we'll let you keep £40 billion plus, we'll agree not to investigate, in fact to allow the swiss to tell us what when how and who we can investigate, and in fact, we'll cede tax sovereignty to switzerland and their tax avoider friendly regime.
Britain gives up sovereignty to Switzerland and £40 billion to tax evaders
