Re: HS2 or FTTP?
Maybe. But probably not if you include the benefits of the construction work. Right now there are thousands of people (maybe tens of thousands) in gainful, well paid, employment because of HS2.
I'm not a fan of HS2 because of the environmental impact but I have to acknowledge that the benefits to the economy go beyond 'getting from A to B more quickly'. Just being able to build it and having all that entails is a benefit to the economy.
