Their is actually some truth in that it's same with banks you deposit they issue an IOU. You don't actually own the money they do but when you request it you get it unless theirs some bad situation going on.
The entire financial system of the world is based on trust and faith. All currencies are Fiat, meaning they don't have any real value other than the government saying it does and the people agree to use that as their means of exchange. Wars were fought to prevent this from happening, and to make it happen even to this day, presidents were assassinated, coups were enacted, secret meetings of rich folk on train cars in the dead of night. If you look at the last 100 years of world history a lot of the wars fought by the US and NATO were against countries that did not have privately owned centralized banks. "Give me control of a nation's money and I care not who makes its laws." Attributed to the Rothschilds but it is the Modus Operandi of the 1% of the 1%. The ones you don't know exist because that's the way you want it.
Nicaragua had a democratically elected president that wouldn't play ball with the US President, Reagan, so he was removed from office via a proxy war and a new "president" was put in his place that would do as the US government wanted. And so a centralized privately owned banking system could be set up, the true reason for the ousting.
From what Britannica says on Nicaragua, "The Central Bank of Nicaragua, established in 1961, has the sole right of issue of the national currency, the Córdoba. The financial system had been dominated by the government-owned Finance Corporation of Nicaragua, an amalgamation of the country’s banks established in 1980, but by the early 21st century, several private banks and microfinance institutions had been established."
What other reason would there be to move from a government owned and operated banking system to one owned by private non-public banking institutions?
Its a bit off topic and of conspiracy, but this is my thread. Mundo posts as he Pleases.
