What you need is debt free currency. The real problem is the FED and fractional reserve banking. Money does not have to be backed by anything, as history has shown many times.
The English built their empire on the tally stick. Yes you heard that right, their taxes had to be paid by a stick. As a matter of fact, the tally stick was one of the worlds longest running currencies.
Lincoln bought and paid for the civil war with greenbacks, backed by nothing. As a matter of fact, the country did so well with greenbacks that the bankers had Lincoln killed to stop it.
If we want to back our monies with something, I suggest something with massive supply, like silver maybe. Gold may be too easy for the powers that be to corner.
I’m no expert, but I am aware of the concept of debt free currency. I think it is do-able, and has been done, as you indicate. But I think it’s one of those “taboo” topics that people aren’t supposed to talk about because if people caught on that the massive worldwide debt is all a deliberate ploy to keep us enslaved, then there would be a Great Awakening.
