OP - You are misunderstanding the purpose of government.
The purpose of government is to control the people and harness their labours, for the benefit of maintaining the status quo. This is done by understanding what is happening in the world, what is likely to happen in the future, and to mentally prepare the masses for changes that will inevitably occur in a timely and measured manner.
Every 'developed' county operates the same system. You have two parties, both acknowledging the same inevitability (at this point it is the acknowledgement that financially the country is no longer sustainable and that too few people are paying into a system that too many people are drawing out of), and so both parties talk/argue about the issues, all the while keeping the populous focused on the fact that contraction is coming and conditioning them to accept the situation when it arrives.
One party will be blamed, but the big secret no-one tells you is that whichever party was in power, the same thing would have happened. You have the illusion that your fellow countrymen voted in this status quo, but in reality those who govern, those who place them their, those who legislate, those who finance, and those who plan, do so in their own best interests.
Government tells you exactly what you need to hear. That is what they do. So long as you pay your taxes and cast you vote, and so long as you are happy to maintain and enforce the status quo, they care not a hoot about you.
The purpose of deficit cutting is not to achieve anything. It is to prepare the people for the depression in the economy that is going to happen. It is not 'might happen', it is a mathematical inevitability in each country. The discussion points of ministers are designed to create discourse among the people, not seek a solution. Those in government know firstly that they are not the ones who pull the strings, secondly that they are privileged to be in a position to act in the best interest of their families prior to everyone else, and thirdly they learn how countries are really run.
How many people in government do not fail to act in the best interests on their families BEFORE the rest of the population know what is happening? How many people in positions of understanding do not become stronger, more wealthy, more secure family units? And yet for the rest of us, I'd say maybe 40% of us can go a generation without noticeably improving the wealth of our family units.
If you believe that government is there to debate choice with you and act in your best interests, then ask yourself why your food bill has never gone down in price over a year anytime in your lifetime? It's not like apples have become harder to grow, or more nutritious. It doesn't cost more today than it did 10 years ago to grow a potatoes or make a loaf of bread.
No. The £ in your pocket gets smaller and smaller every year, and that is because the debt in the country gets bigger and bigger every year. The government has reached a point where it realises that it must address the issue or default. It will not default. It will take us to war, because war is the greatest money generator known to man, and at the same time, offers both an incentive to the people to accept serious austerity (for the war effort), and a reason to blame an enemy for the collapsing economy at home.
