Unsurprisingly in many cases the #tax paid on earned income is twice the proportion paid on capital gains... part of this is an explicit support of #investment (which given low levels of investment in the UK, we can safely say is a failing policy) and partly because CGT is so structured to allow all sorts of game-playing & manipulation by rich holders of capital.
The solution (as the FT would argue) is partly tax simplification & partly a refocusing of tax altogether!
