It is very simple: Money is created by debt. Modern paper money started as a debt certificate for deposited gold coins in a bank. The bank was clever: it knew that not everybody will come to collect his gold deposit at the same time and issued double and triple certificates on the same gold, it did not even own. That works, because the paper certificate (= paper debt money) itself can be used to pay for goods -no need to carry the gold around. And good for the bank: It can either issue more certificates than gold had been deposited, or even use the surplus gold of the depositors on their own. -To lend out against interest (a huge gain -no own capital needed) or even spend it for a nice building or to pay the bank owners and managers a generous return. It worked as long there had been no bank run and as long the bank kept a MINIMUM RESERVE of gold to pay out if somebody asked to cash the debt certificate into real gold coins.
Modern money is in fact a pyramid game. And the MINIMUM RESERVE (by law) is only 10% or even less! And this reserve is just again in money -not in gold!
There is always less money then debt, because it has to be paid back with interest on top. So either there has to be printed more money, or somebody has to go bankrupt and loose his money to enable others to pay their interest.
Now comes social economy:
If the economy in a country grows and values are created, the land can print money according to the value of the assets it creates.
The more money has been printed, the more interest must be paid back. (Also interest on interest, which has a leverage effect)
When the amount of interest debt becomes more than the economic growth value, we can see what is called "The Scissor" - Growth of printed money and economic growth go apart and if the imbalance is too big, the money system must crash.-The huge interest pile cannot be paid any more by the real economy. It has to be replaced by a new one, and the game starts again. The US used the Petro Dollar to print way more (multiple times) currency than their economic growth over 50 years. The artificial demand enabled them to buy valuable assets and invest in other counties way cheaper with their printed money than other real economies were able to do. It is a treason scheme. (the value of the currency in total should mirror the assets and economic potential of the country) The artificial demand created a higher exchange rate, thus the players were able to buy more with an overpriced money. This will end. They went too far.
Trump seeks to control the oil to postpone the immediate crash -which can happen any time...
It is market psychology. Therefor he creates one hype, scandal, war, provocation etc. after another. When the market realizes what I wrote and draws the consequences, the crash will happen immediately and suddenly. BRICKS is the nail in the coffin of the dollar, because a lot of the artificial demand (USD as a general trade currency and for oil trade) will fall away. Therefor Nordstream, Ukraine, Venezuela, Iran,... He needs the Europeans to buy more Dollar or it will be over ...
I think it will not be enough. There is too much cash in the pool. When it starts to flow back into US economy, we will see the worst inflation ever and social unrest/ civil war

Debt and money grow exponentially and economic growth is linear!
With this graph we can also see what Corona really was about.
It was fuel into the fire. It enabled to refinance rotten over-debted companies to keep them alive. Too big to fail... Banks would go bankrupt too, if they would have to apply the rules and send the big debtors into bankruptcy. Too massive writeoffs (like in the real estate crisis 2008) - better for the banks is to give them more money and sell the debt papers (which then look good because of the fresh money to pay the rates) to funds, who then sell these further as fund shares to the stupid public (old granny and dad who invests "riskless" for his retirement). Each seller gets his generous margin ...
