Abolish capital gains tax.

Maybe a contentious one (and I'm perhaps being a terrible entryist trot here :-)), but I'd quite like to have a serious debate around why cap gains are taxed separately to income.

In my view, the seperation between the two is purely an ideological one, based in the capitalist assumption that 'wealth creators' should be especially rewarded for creating economic activity and therefore employment. A claim which I've never actually seen any real evidence for. If anyone can provide some, please do!

There's also practical reasons for this. Treating earning income as capital gains is a common tax-avoidance technique, and this would close that particular loophole in one fell swoop, as well as simplifying the tax system overall).
