The UK cannot buck that market, the Magic Money Tree has limitations, we could borrow more to create growth but we have not been doing that, borrowing/QE has predominately been for social improvement. As Murphy points out the UK is not obliged to include QE as borrowing, it does so to retain the confidence of financial markets by being transparent.
If you were to read it again you'd see that Murphy suggests that there could be no need to use the financial markets at all. See his commentary on diagram #2.
It’s not about economic theories it’s about balancing the budget, successive governments have failed to do that for many years, for political gains they have been spending too much on social improvement and neglecting growth.
I agree, I'm sure most people will agree, that governments have failed to spend on 'social improvements' but that has nothing at all to do with 'balancing the budget', though it certainly does neglect growth, in that state spending, as Murphy's piece demonstrates, is a driver of growth.
By 'growth' I mean creating economic activity which supports job creation, payment of real living wages and a decent standard of living for all citizens. What do you mean by 'growth', Katie59?
