This is the fundamental problem, people have to believe what is being done is right. At the moment a large section of society that is doing essential work is taking a hit. This is the typical Tory way of simplistic spread sheet accounting. The trouble is it's a race to the bottom.If you feel quoting your belief about Portugal, the USA and the UK re spending, austerity and the relative merits of Keynsian approaches, backed up with graphs of absolute values and then typifying the problem with spending as a % of gdp as an economic measure, relating to Gordon Brown is an "Analysis", bully for you!
I suspect it's more complicated than absolute positions will admit!
I will say the absolute value of government spending in this banana republic has put a lot of people out of work, including police, nhs, fireservices and a range of other public sector workers, whilst freezing those who survived the axe pay! At this point I'm not sure your absolutist graphs will convince many we haven't actually had Austerity, perhaps you could trot out a household analogy for them!
Unfortunately I don't think any of the current political options or even the BOE are capable of running the economy in the correct manner.
The current economic progression is unsustainable so it either all crashes or slowly gets worse and more people get poorer.
I don't see anything that is going to generate sustainable wealth for the majority.
