Keynes always stated that as there are so many variables for successful economic policy then solutions have to be constructed to for the current times and problems with solutions for other times not being appropriate.

I quite enjoyed reading that MM piece - based on the concluding remarks, I fear that the answer may well be that there is no answer.
The unhappy realisation that there may indeed be no well measured or well developed answer to this vexed question of the need for a sustainable economic policy may not necessarily have had any great impact around the world in times past.
Sadly, in the present (and future), the absence of answers to the questions many are now posing about how we proceed on the path towards economic stability and growth, may well have catastrophic consequences for everyone in this increasingly globalized society where the immediacy of information, the bellicose nature of the many who make up its number and the availability of weapons of mass destruction presents a threat to mankind hitherto unseen in such a potentially far-reaching way.
There are some very good solutions for the UK and Europe but they won't happen as politicians would have to implement the unthinkable which would throw away much spent political capital and dogmas and it would mean many of their public office cronies losing their jobs, through the exposure of their total incompetence or they being surplus to requirements.
UK:
The cast DC - Prime minister, GO - Chancellor, NC - Deputy prime minister, MK - Mervyn King head of BOE.
1. DC: It is politically much easier, while you are in office to borrow or tax to spend other peoples money to provide an electoral feel good factor.
2. GO: I'm raising taxes to help our spending plans, that should put more money in the electorates pockets, especially as the money raised will be spent in Brussels on their budget increases and any third world country where the local despot needs help with his retirement fund from our ever increasing over overseas aid budget. I must make sure I pluck the tax feathers, where the electorate are unlikely to notice. How about a tax on hot pasties?
3. GO: Its not working. MK: I can either drop interest rates to even nearer zero and / or print lots of money or use QE to debase the currency through higher inflation. GO: You know I don't understand economics, so whatever.
4. GO: Still not working. MK: No, the inflation rate is higher than wage rises, so wages are dropping in real terms and inflation is higher than interest rates so savings are devalued. GO: Apply some more QE, that will fixed the bond markets, so I can borrow oddles more for next to nothing. MK: It will rasie inflation. GO: Who cares we've both got inflation proofed pensions.
5. GO: Keep going on the QE as the capital debasement on house prices will minimize their drop and bank losses. This will help our mates the banksters and of course us politically where we largely own a couple of them.
6. DC: We will implement minority rights and political reform legislation, as we might get a few extra votes and it will distract people away from where we haven't got a clue what to do on the economy.
7. DC: Let throw as much money as possible at the new modern religion of Climate Change and anything with "Eco" in the title, we might pick up a few votes here, and of course it will help our land owning relations, where they can rent plots for some of the wind mills. MK: What about the energy bill increases to pay for this, people will suffer. GO: No we won't, me and DC have rent free all the bills paid accommodation.
6. DC: Lets huff and puff on how we are going to repatriate powers from Brussels and do some supply side reforms, which is probably currently one of our best hopes for growth, while doing the exact opposite by nodding through more EU directives and treaty changes and making our industry even more uncompetitive. This should help our growth.
7. NC: We can go for growth by selecting the ideal candidate through the coalitions Buggin's turn rules. So what if have an anti-business anti-enterprise, anti-entrepreneurial, anti-profit business secretary, who does nothing but moan about business ethics, its his turn. There you go that should get the private sector booming in no time.
8. DC: We will go for growth though infrastructure projects by banning a third runway at Heathrow, so we don't fly to tiger economy destinations, where we could be doing export deals. Instead lets build the politically easier un-needed duplicate railway. There you go, you trust us to make the difficult decisions for the good of the economy.
9. GO: Help 0.7% GDP drop. DC: Try a distraction, this is ideal, we are holding an expensive International sporting events on our home turf, is always a good one, especially if the local mayor gets into the swing things and adds a few of his own stunts
10. GO: It's still not working, I'll blame the Euro, opposition, bad weather, good weather, Jubilee holidays, anybody but us where we are doing such a very good job.
DC, GO, NC and MK: We might be stuffed at the next election, but economically so will the electorate and you haven't been getting our MPs and ministers salaries, expenses or our inflation proofed gold plated pensions. Ha, Ha. Toodle pips, Were off to my new jobs in Brussels as Eco, Climate Change, Equality, Gender Awareness Outreach Commissioners, on a mere value for money €300k each, tax free.
Anybody for a celebration hot pasty.
