Currency today is created by private institutions who create as much money as banks and governments desire. This money is created out of thin air, literally by punching a few keys on a computer and sending tiny currents of electricity to a screen which displays whatever number the private corporation wants.
It is not backed by anything of value, yet these private institutions charge interest to governments and private sector borrowers.
For every dollar created and loaned, the magical money-lender demands that dollar back plus interest. Since the lender is demanding more than was created, it is mathematically impossible to ever pay off debt, because the interest simply just doesn't exist.
This system ensures that the human race will always be in debt, and this system is the new slavery, meaning that when we owe money in this fashion we are not free to use the full power of our labor and resources to improve our communities and infrastructure.
The IMF has just reported that total global debt is now at a staggering $164 trillion, which amounts to 225% of total global GDP. Every person on this planet could turn over everything they produce for the next two plus years and we'd still be in debt.
