That is very welcome, but I do not believe in the immutability of a certain level of tax revenue and that, whatever we do, we cannot change
that level because somehow the world will not produce more than 38% of GDP in tax. It is just a question of collecting that tax and enforcing the tax rates to ensure that the big international corporates, in particular, pay their taxes. When we do that, we will see a substantial increase in revenue. Of course there are countries where overall tax revenues are substantially higher than ours, and they are not necessarily countries that are doing badly economically; they are countries that are doing well, but a higher proportion of their economy is in the public sector. Those countries have higher taxes and higher public spending, and they are civilised societies, too. The countries with the lowest levels of tax and public spending are often some of the poorest, where the gulf between rich and poor is much greater and, generally speaking, life is less pleasant, particularly for the poor and the less well off.
I look forward to more enforcement and a higher tax take by enforcing the existing tax rates and ensuring that people, particularly the corporates, pay their taxes. When it comes to taxation, the behaviour of the economy is crucial.
