I use an explanation using elections. Where cities, counties, states etc. (what applies in your $country) count and aggregate their values upwards until it's clear who has won on a national level. :)
As long as the Federal Reserve exists, I don't think this is possible. Given that it is just as PRIVATE as Federal Express, it is not actually the government that creates the Federal Reserve Notes, but an external entity. [1]
This 3rd party does get interest paid for that.
So the government wants an amount of X dollars to exist.
The FED ceates X but demands Y interest.
However, only amount X exists and X+Y does not.
To pay back Y,a new amount has to be created.. Over which interest Z should be paid, etc. etc.
In other words: it's impossible to pay back the national debt to the guys who have claimed the magic right to put ink on some cotton and call it a million dollars. Dollars which can no longer be exchanged for silver as was possible a few decades ago...
Now why do these banks keep loaning money? Well they already own the country since the default of 1933. The current collateral is every U.S Citizen and their future labor if someone has a birth certificate!
The only free people in that sense are those who have a Sovereign/Freeman of the Land status, living under Common Law instead of Maritime Admiralty Law.
Youtube: "Have you met your Strawman?" & "Choosing Freedom" for more of an introduction..
"No, today, in our crazy money system, the government has to borrow our money into existence and then pay interest on it. That's why they call it the National Debt. All our money is created out of debt. Politicians who focus on reducing the National Debt as an answer probably don't know what the National Debt really is. To reduce the National Debt would be to reduce our money -- and there's already too little of that."
"No, you have to go deeper. You have to get at the root of this problem or we're never going to fix this. The solution isn't new or radical. America used to do it. Politicians used to fight with big bankers over it. It's all in our history -- now sadly -- in the distant past.
