thing is the grey book even notes "behaviour changes", acknowledging that taxes will result in the income/asset base being taxed moving. yet Corbyn and the left will say it wont. and that impacts on the other tax revenue streams, not accounted for.
All proposed tax legislation includes a quantified reduction, usually huge, for the behavioural effect on taxpayers of a new or increased tax. Apolitical. The IFS do this too to an extent, within the limited time span available to them.
The disparity is in the £billions were tax. Whether it be a Tory or Labour tax.
