I got to this post and then stopped reading!!:
Irrespective of your political persuasion it would be very difficult to argue that VAT was regressive, as it allows people to avid the tax by limiting spending, whereas income tax/NI gives Zero choice to avoid any tax. As for it having less effect on the rich, it has the same effect on everyone it's just that some people have more money than others...a fact that people don't like but is inevitable.......
and then couldn't avoid reading this gem just as I posted!!:
The VAT on fuel (and the VAT on fuel duty) puts the price of fuel up, which puts up the price of pretty much everything; food included.The Government need to ditch the Bank of England. Stop borrowing money and print it for ourselves.
