Tax & borrow works for every country why wouldn’t it work for us? We’re in the shitter anyway so why not give getting out of it a go and if it doesn’t work we can come back to the shitter
I’m not worried about any Brexit impact if Labour get in power because the outcome will be BRINO or remain. If you cannot accept that there’s no point discussing anything.
Renationalisations would be completed bonds for shares as it has been done in the past. Costs aren’t just wasted if those plans go ahead because if you’re paying X amount of money you’re getting an asset worth X amount minus possibly any premium you have paid on top to acquire it. You’ve spent X but still have X or very close to it on your balance sheet.
You should read the grey book if you want to find out more about costings.
