Again you are taking shelter in a same line of thinking viz; US debt of 100% vs its GDP.
By above logic, japan would have been Kaput, which has 250% of its GDP debt.
Simple following question again:
Which currency will replace the USD in 2050?
Is it so hard to answer this?
Convince me or get convinced.
Black or white.
There is nothing in between.
Don't be a traffic signal with amber light.
The answer is easy.
Man you are not getting crux of the argument ...
Although it is all off-topic and we should have discuss in another thread but let me explain you in detail. The working of financial world is entierly different from the way you are thinking... this is all based on a complex automatic and free floating system of demand and supply .
If you read the history US Dollar actually collapsed in 1973 during Vitenam War and the US Dollar we currently sees is entierly different from the dollar introduced as world currency at start of 19th century ...
In the start of 19th century dollar was redeemable in gold at fixed rates as a result US was bound to maintained a significant reserves for the note printed ,,, in 1973 US did actually bank corrupted and refuse to redeem the dollars but then they introduced a new dollar that has redeemable value but for this they had to create a demand to keep it as a global currency and for that they introduced OPEC where all of the world oil has to be traded in US Dollar and here they created a demand ...
Now consider a world where oil is traded in commodity other than dollars than what would be the imapct? Demand of dollars will reduce sharply whereas in no way US will be able to remove the supply from the market as it means providing services and goods against all those papers but which is not possible and resultantly by out of control market factors it will decline sharply ...
Such an event can always happen and China is very much in position to make a such a move being one of the major oil consumer but right now any ty will harm unstability will harm China as well and can restrict China to become undisputed super power ...
Right now China is investing in military and spreading its influence and once they have significant influence so that they can manage other countries on stand alone basis they have to simply dump the US Dollars reserves they have and have to push the suppliers to sale oil in any currency other than US Dollars and US economy will collapse ...
Collapse os US is simple economics, the demand of the most profitable product is now out of its hand with demand of US Dollars coming from China, India and middle east whereas Europe has already opted for Euro ...
Now we can see clear tumoil in middle east and it will not be long enough that middle east country seek shelter other than US and CHina will be able to provide the same (which currently they are not) and hence demand of the most profitable product will start falling ... Unlike other products US dollar is not a consumable product and for deamnd of every single dollar US will record a loss of 99.5% ...
It is just of matter of time ... not in very near future but probably in a decade or 2 , world economy will take a big hit and US economy will collapse ...
