re: Four principles
It's still interesting to note that you still plugging the line that 'it's legal, so there's nothing wrong with it'.
What's even more interesting that you still can't bring yourself to comment on Adam Smith's Four Principles of Taxation in this instance. Instead, we get a soft-shoe shuffle - from someone who belongs to the Adam Smith Institute, no less!
The irony of the whole situation is that you whine and sneer about groups like UK Uncut, but they seem to have a clearer idea on taxes being equitable between persons than you do!
An outsider would think that you should therefore have nothing to do with the ASI, but of course anyone possessing a reasonable smattering of economic history can recognise that the Adam Smith Institute doesn't in fact promote all of Smith's work but instead cherry-picks the parts that support its own biased and morally corrupt agenda.
So crack on, fella. It's always entertaining to see the moral and intellectual somersaults that a fat cheque can encourage.
