Because you don't have instruments to controll the monetary system. Deflation can be way more harmfull then the inflation. It will completely kill the macro economy of the country. Economists have to struggle it.
Controlling the monetary system is very much a Bretton-woods invention. World economy had been running through the years when you did not have these 'monetary controls', albeit with crashes and depressions. Crashes still happen today. The problem is, economists have convinced themselves and the world that this model works the best. Even when there is an alternative emerging for the taking, they are more interested in disparaging it than actually informing the media and public about both sides. It's a battle of perception than a case of one being superior over other.
A capped reserve gives much less wiggle room to central banks(like the Federal Reserve) forcing them, the Politicians and the Investment bankers on their management boards to actually do their job. While with an unlimited reserve,
you can always "Quantitatively Ease" your way out of any fuck-up.Bretton-woods system ahould ba able to clear the mess after the hard times and make economies more connected with each other. At the 2nd half of the XX sentury
economic science was way more developped then it was years ago, it became an established science rather then just an exchange.
Economists started using different econometric tricks that did not exist before. First, Economies have so many variables ranging from the social, psychological and political that economics cannot really be considered "Science". It is still very much a "Social Science"; a Humanities topic, if you will.
You used the phrase 'econometric tricks'. The same thing as "Financial Engineering". Money is ultimately about power and control. The power to control taxation and interest for governance. What the economists have shrewdly achieved is to
paint these "tools" of taxation and interest as some sort of holy grail for constant growth. When constant growth and consumerism shouldn't even be the sole target of societies.The real problem of US economy (as highly affects the global economy) is welfare. This is a huge beast and politicians still keep feeding it (and probably will continue doing it). Insane amounts of money are wasted for nothing. If anyone think that the current global economical system works bad then he can eliminate welfare before dealing with the other things.
This seems to be coming from the laissez-faire, anti-welfare school. I don't think there is anything wrong with welfare as long as it is not used for political gains. The problem is that this "insane amount of money" has no basis and no accountability.
Imagine a country where all "welfare allocations" were transparent on the blockchain and
every single Satoshi spent was accounted for. There won't be an unlimited amount to allocate because, well, you won't have an unlimited reserve currency to fall back on.
Right now, it's fair game for all sort of organisations that take their share of the pie from the debt financed US budget. The money goes in and nothing comes out. That debt-financed money ultimately reaches the top 1% of people via their companies. The burden of debt is borne by the middle classes in the form of higher taxes, higher inflation.
A transparent, decentralized currency is quite a solution for this whole problem. We never hear the media talk about that. The economists are free to wax eloquent about "fiscal policy", "monetary policy", quantitative easing" and what not. Fancy terms to make people realize that it's all too complicated and the trio of Govts, Banks and Businesses is doing a fine job.
