Not impressed
I'm no economist and I'm not going to start arguing the toss with Tim about all those formulas, although I must say it's hard to take a writer seriously when he uses terms such as "lefty". However in the context of the current worldwide insanity (central banks printing like crazy to buy up bonds and stocks) my naive view saw nothing in the article which really sounded all that bad, relatively speaking!
The average voter will not understand the formulae either but may be very tempted to vote for someone like Jeremy Corbyn as a change from all the smooth Westminster lookalikes infesting their TV screens every night.
