I reccomend that you read john redwood in last sunday mos.in which he quotes treasury stats indicating the exact opposite of your assertions.
The top1% of taxpayerspaid 25% of all tax paid when the rate was 50%
But 28% when the rate was reduced to 45%
It therefore proves that the mega rich and it is the mega rich will tolerate such lower tax rates and not take steps to minimise their tax bill.
He therefore advovates an immediate reduction to 40% in the budget next week!!
These covered different years and the share of the wealth increased over this time?
1% of the countries tax payers would benefit from this decrease. That 1% holds 13.7% of the countries wealth.
To give the 1% a tax cut while we are looking to cut £12 billion from the poorest, how shall we say, looks a tad insensitive.
