The whole burden of taxation has been steadily shifted downwards since 1979, poll tax, VAT, et al. Top rates of tax are now historically low. The result has been massive shift of wealth upwards, which is the whole idea, and massive deterioration on public services, which is just the inevitable "collateral damage".
Indeed, if you compare a pie chart of tax in the 1970s with tax now you can clearly see that VAT has replaced tax once paid by UK top earners.
The thing that few people understand is that tax does not fund anything.
The purpose of tax is the control of inflation.
When governments collect tax, that money is destroyed.
Take a piece of paper, draw a line down the middle.
Write "One pound" on one side and "I owe One pound" on the other.
Tear down the line. Spend the bit of paper with "One pound" written on it into the economy and put the bit with "I owe One pound" in a drawer labelled "National Debt".
Congratulations! You have just created money, spent it and are now running a deficit.
So, what happens when you tax back one of your "One pounds" ?
Where does it go?
It goes into the drawer with the "I owe One pound".
And then what happens?
You have a drawer with a "One pound" and an "I owe One pound".
That sounds suspiciously like the answer is zero.
One minus one is traditionally zero.
That, of course is not how government accounts for tax.
Oh no. They pretend its money they can spend. But its not.
No liability survives contact with its issuer. All tax is destroyed. All spending is new.
