From The Guardian:
Mark Wadsworth, the head of the Campaign for Land Value Taxation, said: “The minority with a vested interest in high land values will no doubt celebrate higher values, saying that is shows the importance of land to the UK economy.
“In truth, land values are not a net addition to national wealth, they merely represent the benefits that accrue to landowners because of government spending on public services funded out of general taxation; land values are actually just a measure of ongoing transfers of wealth from taxpayers to landowners and a zero-sum game.”
It's nice to have a journalist contact you for a quote and then publish it verbatim, unlike my experience with The Telegraph who twisted everything on its head (not that I didn't expect it from them, but all publicity is good publicity).
