I have never supported a change to government policy more vociferously in my life. Having worked as staff to a professional services firm, I can tell you these aggressive tax avoidance schemes are rife. They are also deeply unfair. When you know that someone who earns twice your salary is paying less effective tax than you are, because they are in a position to incorporate and you are not, you really do begin to question the existence of class warfare built into the "system".
