Paul Grignon, who produced the popular "Money as Debt" animated cartoon, has just released "MAD2: Promises Unleashed".
It
is another entertaining tour of the money system. This time, unlike
MAD1, he devotes significant time to the idea of interest payment
recirculation. He concludes that despite the way interest payments
recirculate, the system is
still unsustainable, because the
money doesn't have to be respent into the economy in such a way that it
can be re-earned by the borrower. It can be relent by a secondary
non-bank "real" lender, it can be hoarded, it can be gambled and lost
in the currency trading markets etc.
As far as I can tell, this argument continues to be invalid. I went
back and reread the discussion of this topic between myself, Ryan,
Gaute and others to check this idea.
The basic idea that if less
than 100% of the loan is respent into the economy it's unpayable is
true, if you assume the existence of no other money in the system. But
this is an oversimplification which produces nonsense. As long as there
is any money circulating elsewhere that you can earn, the loan can
still be repaid in full. Even if there's a continual suction of money
out of the system, the remaining money can simply increase in velocity
to compensate until new money is created outside the context of an
interest paying loan.
Now, moving on. Grignon proposes a new currency scheme at digitalcoin.info:(btw it makes references to a video on the site)
http://digitalcoin.info/Digital_Coin_in_Brief-June7-09.pdf
The key innovation (?) in digital coin is that it actually consists
of two types of coin, "permanent coin" which is basically a pool of
coins of fixed size and "credit coin" which is a time-limited
(demurrage) claim against goods/services of the issuer. It's a personal
currency. The idea is to balance the merits of both schemes. Anyway,
regardless of what you think of the videos or my explanation, read the
PDF - it's only a few pages long.
