I'm no economist but I doubt you can promote growth simply through tax, tax, tax. However over the last 40 odd years there has been a massive growing gulf between the haves and have nots, we are one of the most unequal societies in Europe. Would you not agree that for a cohesive and content society that this ever increasing economic disparity needs to be addressed? 'Progressive' taxation is one obvious way this can be done. The rich had far higher taxation under Thatcher, I'm not suggesting that we go back to those rates but I don't see anything wrong with upping them and those who have benefitted paying a bit more.
