Silly answer you know well that would result in a minscule saving. So to sum you can come with no way of creating savings in council budgets. So your whole argument is worthless. "I want better roads and I can not think of any way the council can afford it. The council can just make the money appear by....fill the rest in.
A silly question deserves a silly answer... Im glad you picked up on that.
If you are prepared to delve into council funding, you need to understand their exact spending. Im not talking about their colourful little leaflets they send out each year, but a proper breakdown of their spending. How about the Gov't grants given to councils that are supposedly spent on potholes? Break it down...
You can't ask a question like "where do councils get their funding from?" when you almost certainly don't know the breakdowns of their spending "including third party resources" yourself. We've read in the papers that they're skint, but then Boris Johnson has reportedly said a number of times over the past that his salary is not "enough to live on".
Lets deal in facts if you want to but then prove to me that councils are skint to the point that they can no longer maintain a legal requirement to maintain the road infrastructure...
