The current banking system is unsustainable in four ways.
1- The accelerated creation of money out of thin air (quantitative easing) is unsustainable. It both waters down the value of the money you hold (inflation) and widens the gap between the rich and poor.
2- The current explosive rate of new money creation leads to an equal expansion of the production of goods to absorb this new money. Easy money means unwise development at the expense of Mother Nature. This factor alone is the greatest driver of resource depletion. Use of irreplaceable recources will come to an end one day.
3- The concentration of immense power into a few unelected officials hands is never sustainable. The Federal Reserve of the USA is a body of 5 unelected officials who sets the interest rates and rates of money creation. With this power they hold the worlds economies in the palm of their hand. Such power has always been overthrown by oppressed and awakened people.
4- Monopolies are not sustainable for the same reason. We are about freedom of choice. We believe people should have a choice as to which currencies they can use. Ie-Fiat currency created at alarming rates by out of touch and greedy bankers or money created by "the people". With the advent of cryptocurrencies we now have that choice. *
The false dream of financial freedom under the current system
The term financial freedom is thrown out often to entice people into some wealth building seminar or business. It implies earning enough money to be free to do what you want when you want. Further it means not being tied to a "Job Job" with no time to enjoy the money you've earned. But until we address and change the money we use no one will be financially free no matter how much fiat currency they own. Why? Because they are still slaves to the few men and women at the Federal Reserve in the USA who set the interest rates which effects every economy in the world. These unelected officials can either accelerate the economy into a bubble or crash it into a depression through an adjustment of the interest rates a few points up or down.
Also these same men determine the amount of money to be created (out of thin air). This gives them the power to water down your money, to the point that now the US dollar is worth just 4% of what it was 100 years ago. This devalueing of fiat money is quickly accelerating in recent years with the advent of "quantitative easing". (the printing of money without restraint or oversight.)
This is financial slavery to a few men. We are not truly financially free, until we are free of this slavery...no matter how much fiat currency you have in your bank account. Just ask those who lost it all in 2008.
