I Made other post of what is the money actually but this one describe simple way

The money the fiat currencies are debt.
In otherwords every debit is someones credit.
The money value created of debt will be impacted the people ability to serve their debt but we all ready see that people ability to serve the debt are bad.
If nobody can't serve the created debt anymore then value of money will fall becouse If person have lost all ready home becouse of debt there is nothing more to lose in order to keep him to serve the debt.
So the goverment and central banks must keep the people ability to serve debt with political methods and financial system it's like balance game they can't go too much left or right they have to keep it middle.
So If people ability to serve the debt are good the currency value fall also, but If their ability to serve debt are too bad the value of currency will fall Even harder.
The money is created of the debt in order to keep balanced value of money people situation can't be too good and not too bad but exacly the middle class or little bit more poor than middle class that's perfect climate to keep money value quite stable but USA Went all ready into too bad so the debt can not be served no matter how hard anyone will work same situation in UK and Eu.
But USA average people have gone into so much debt that they can not serve money.
Off course dollar is strong now becouse of the shortages of dollars but it's temporary becouse of the debt can't be paid and people cant serve the value of the money anymore becouse they got no ability to serve the debt and keep paying and in this conditions the foreign bond investors not stupid they see that no point to invest more money in USA becouse of people are allready in the large burdens they all ready can't serve anymore.

So what is the money for example USD, it's the liability of debt the currency strenght will be determined of debtors conditions how good they can serve the debt.
The Fiat currency system it's modern slave system when the Bond buyers will invest into countries bonds so the country can print money If the country are attractive to the Bond buyers why Fed cant lower the rates is that there is no Bond investors enough.
Bond buyer are like slave master or owner whos buys the slaves and slaves are kept in "bondage" to serve their slave masters the bond buyers who invest into bonds eg, slaves.
In USA the debt are all ready served bad and therefor it's not attractive place for Bond investors.
Every county need to increase the productivity and effientie in order to attract bond investors.
If we look at the around the world the investors confidence about China and Norway might be biggest since in china strong goverment regime will make sure slaves are in check and productive as possible.
Norway in other ways just with strong goverment and good workers productive actions.
So the country attractive or not to bond investors it depends on If the Bond investors see the country whole society as productive and prosperous.
But nothing more attractive country then china becouse of slaves are strongly in check and highly survelanced to make sure they produce as much as possible.
No wondering why the WEF said china is the role model."
Becouse off course it's all about profit and productivity of the people of country.

It's visible that USA is not atteactive to bond Market investors becouse the Bond investors the nowdays slave buyers sellers the modern day slave traders don't see anymore that there are good productive slaves in USA.
