Make it a legal requirement that those purchasing goods that have VAT attached to them can see how much VAT has been spent when given a receipt at whichever retailer they've purchased products from. Make it mandatory that people see how much goes back to the Treasury.

This needs to be made mandatory so people up and down the nation can see how much money they spend on goods which have VAT attached to them and how much goes back to the Treasury and how much goes to the retailer. It is important people see this so, hopefully, in future, VAT for certain things can be reduced to make the cost of living crisis something future generations do not have to face as harshly as we have had to.
