Sir, a small observation, if I may; we have been devaluing our currency almost since the inception of the United States of America. As I look about me I see many things that should be attended to, but I do not see destitution.
Regards.
You said: "There is, I should think, a point where further inflation will make a debt unsustainable"
This is a very important point... we have issue that the debt invokes that is being addressed by the world, of which we may try to ignore but the world is aware of our debt... and how our economics is tied to the position of Reserve Currency. When the time comes the world moves from the system of "Petro Dollars".... as is and has been a discussion in the Middle East for far more than a Decade, first led by Iraq under Saddam and by Quadaffi, both of which we attacked... and Iran is now well aware that the power of American Sanction, is only done by the system of Oil being tied and traded with the U.S. as the Reserve Currency.
But what they have found is, Europe created financial system to avert the impact of sanctions, by setting up means to Trade Oil in other currency.
This is much to do about the war posturing and fictions of drama that is targeted upon and against Iran. America forgets, that the world on Nation is no pleased by the U.S. position of exiting the WMD agreements, and invoking also a Trade War while standing against Climate Change and expecting at the same time for Iran to submit to American Imperialism.
The more debt increases and deficit rises, it is a recipe for the world to know, the U.S. can only pay its debt based on "borrowing even more"... and that means other countries are supporting America... and being "denigrated by America" at the same time. We are biting the hands that feed us, and attacking the nation that supported us.
Yet, people are still lost in the delusions that America can again promote itself by Imperialist Agenda. It is not to be!!! Nations of the World, are making "COOPERATIVE AGREEMENTS"... while America is destroying "Diplomacy"....
All Nations except America and Mexico has joined the "Cooperative Agreement Platform of the AIIB", Japan drafted its papers to join, and the abuse Mexico is experiencing by the acts of America... will see not only will Mexico Join, but the region of Mexico and Central America will see a backing by China, accompanied by improved "trade agreements" that will give Mexico the means to export its goods without dominant reliance on America to buy its exports... Central America will see support from China, Russia and Europe... and the come along's such as Spain and other nations will support the process. Venezuela has massive Oil Reserves... and the collective of China, Russia and Europe and the UN will not allow America to think it can wait and promote even more hardship on Venezuela with a vain hope to gain dominance by any contrived means to have influential dominance over or upon the out come of Central America.
America missed its change to uplift the Central American and Mexico region to strengthen the North American and Central American stature as a unified forces..... and it has denigrated the lives of Mexican and Central America People by the vile inhumanity of the acts of damages to "families" with no regard for the fact that Mexico and Central America above all things, is a region of the world that hold "the value of Family" above all things. They will not by any means forget nor forgive America's inhumanity and certainly not when the time of need is great and the destitution is widespread.
We have to see the big picture and the blindness being promoted by this Administration and its Republican Senate, is lost in the delusion that America is still the dominant nation it was, Post World War II... and that has not been the case since the 1960's and 1970's.... !!!!
We ride on false vanity and delusions of superiority, while within the society the spread and expanse of generalized "ignorance is being exposed more and more each day of how expansive it has become"... it is being exposed everyday, how illiterate America is when it comes to "Civics" and Respect of the systems of Governance, the System of Laws and the Systems of Congressional Responsibility..... We've been led among a mass of many to chase the delusions of the past of thinking America can recreate and re constitute the system of "white nationalist of and by the madness of wealthy white male dominance" The Republican followers stake their lives and the future of their childern upon such madness... and they are blind to the devastation it has historically caused and the devastation it has set in motion to continually cause at this time in American History.
