That doesn't distinguish between tax evasion and tax avoidance.
For what it's worth the UK ranks somewhere near the top of the list of tax potential vs tax take.
That's not to say that we shouldn't pursue tax evasion, we should. We should also deal with one of the causes of lost tax which is the hideously complex tax system (the progeny of one Gordon Brown). The current cuts to the HMRC departments that deal with tax evasion are Labour's cuts, the new approach probably in the short term is the least worst option, if there's a retrenchment from dealing with tax evasion then I deplore that.
If you want to pay more tax then you should, fair enough, for everyone with a choice in the matter I don't want to pay a penny more than I should.
There's another reason why I won't be signing and it is this; this petition is undermined by the childish mewling and name calling.
