We are well beyond the point of tax saturation. It's now the highest it's been since 1947, and little to show for it.
Raising it further on any sector rich or poor will continue to stifle growth and discourage investment. Taxing billionaires won’t raise a significant amount unless punitive percentages are applied and many have already moved their liquid assets out of the UK and will continue to do so.
Corporation tax could be raised from 25%, but it is already 17% higher than the European average of 21.3%. Investment is very sensitive to corporation tax rates and any increase will largely “trickledown” to the consumer as happened with Employer NI.
In economic parlance we are now on the wrong side of the “Laffer curve” aka “The rider is fatter than the horse”.
Public spending has exceeded our means since the 1970s but is so unpopular with the electorate that no party is prepared to implement meaningful cuts. The Conservatives did reduce public spending in real terms but this is generally accepted to have contributed to their loss in the 2024 general election.
The recent debacle with the Government attempting to reduce public spending further demonstrates that this is unlikely to happen under the current administration.
The painful truth is we need to slash public spending to have any chance of survival.
The bond markets will throw them under the bus if she pushes it much further, (bearing in mind most of them probably live in houses worth more than 2M.)
They (the bond markets) are deeply concerned the with the clown-car antics of the last couple of weeks, see the gold price if you're in any doubt a storm is brewing.
