"There are no marbles in the jar."
The jar IS the economy. The marbles, paper money.
you can pay for this and you can pay for that...you can collect taxes, spend money, buy thermite, nukes, liquidate assests, trade goods and services, feed your family, invest in stock, buy an ipod, a house, work to get paid, pay taxes, give to charity, do risk assessment, borrow, lend, go bankrupt, redistribute wealth, invest in your 401k, go on vacation, etc, etc, etc...
but it all takes place INSIDE the jar...the jar that only holds 10 marbles.
But the central bank that facilitates this, wants the one that doesn't exist BACK.
I'll say it for the last time...ALL dollars in circulation are a product of an interest bearing loan. ALL of these dollars exist within the economy (the jar). But the bank wants you to pay back ALL of these dollars plus 1.
It is impossible to pay back that one because that one DOES NOT EXIST!
You can talk all you want about buying this, exchanging that, making payments, charging interest, blah, fucking, blah. It exists in the jar with only ten marbles.
And the bank wants you to pay eleven.
I cannot get any more plain than this.
