Crazy really. They never create the interest so at some point there is not enough to pay back all the loans or debt.
so someone has to default. it's built into there system or take out another loan.. also if you put $1000 into a bank they can then lend out $1000 to ten people and when they add that to there account, another 10 X 10 $1000 loans can be made all from the same original $1000 and on and on...that started many years ago when people used to trade gold and the banks then said we will hold it for you and give you a note which then they exchanged.
a lot easier than carrying gold around. but then no one asked for their gold so they thought we can lend out loans and they did and thats where this system really started.. it's flawed and at some point people will see that it's not real it's worthless where as physical assets like gold and silver don't evaporate over time like fiat currency does and there's only so much of it. currency is not money. once it was backed by gold but now it's not and they can print as much as they like or just type numbers into a screen and create it from nothing and then we have to pay back as the slaves you right all a scam.
