I am disappointed that your standard of journalism is such that you have adopted the populist but uninformed view that the lifetime cap on non-concessional super contributions is "retrospective". Of course a lifetime cap is measured from some time in the past - that is what lifetime cap means. If someone has contributed more than the cap since 2007, there is no requirement for them to withdraw it. The significant of the year 2007 is that contributions prior to that year do not count towards the cap. Your talk of retrospectivity and loss of trust is a storm in a teacup.
I read the letters to the editor more closely than usual this week after 2 were quoted in Robert Gottliebsen's column. Interesting comments by Simon. Whilst he says he has done the maths, I think he needs to look further.
