A person knowledgeable of social and cultural matters in Russia said in a TV show yesterday: He said i have friends in Russia, sometimes well educated, but even they believe that the USA and the NATO are enemies that are willing to invade Mother Russia.... Putin owns his popularity by feeding this thought deep embedded in the Russian society that the West envies and/or fears them and is willing to go to war with them, in that respect nothing has changed

In the last century or so, is it not our manufacturing capability that has won us wars. I would certainly hope that the government would do as you said and relax some of the regulations to "git 'er done." I'll be honest, I'm not a historian, but from what I've heard, wars have always been good for us economically. I'm definitely not saying they are good, but have helped us back at home. But I guess that really only works if you government has money...
You hit the nail on the head: John Maynard Keynes sawhis economical dogmas proven by WW2 wartime economy, where spending helped boost aggregate demand, which helped create jobs, which gave people money to spend, which made the snowball grow bigger. However before he died in 1946 he remarked that his followers carried out his ideas to an extent he found somehwat scary. Now when we go back into history, most countries in the day didnt have a budget deficit nor a collective debt. What WW2 showed is that when a government surplus, and savings accounts, are spent in the national economy, it gives a great boost. However 70 years later weve become debt based economies, where there is no surplus nor savings to be spent, however politicians keep holding on to the Keynesian dogmas because they dont want to be the one to burst the bubble...
However even in 2008 people called for Keynesian methods to cure the problem, as they felt the free market has failed... But when the markets failed, were they really free ?? Fanny Mae and Freddy Mac were encouraging banks to take bad loans (to people that couldnt possibly repay them, but who cared if the housing prices rose faster than the interest rate) which lead to a housing bubble, not just over at you guys in the US but here in Holland we have a housing bubble too, (luckily it deflated slowly here, instead of a sudden burst)
The problem with macro economics is that there is Keynesianism and there is the Austrian school, and these schools of thought are not only economically opposed, but will require political conditions: Keynesianism is the lefts believe that markets can be controlled by bureaucrats, the Austrian school believes that no man can ever make the right economical decision over another ones life and therefor the markets should not be controlled, just the weak must be protected from the strong, which means the government has only a guiding role, not a controlling one and is not to become involved.
In other words, macro-economics isnt a factual science, its just as abstract as politics. Thats why there will never be a consensus in economics....
