Referring to point b) and an earlier point of yours suggesting
the US is the only country printing USD, what drivel are you trying
to drive home, really? The North Korean won too is only printed by
the DPRK, the SGD by Singapore. If you could literally print money
at your own free will and not affect the rate of inflation by the
slightest, which nation in the world wouldn't be printing its own
currency excessively? Taking your argument at face value, why
shouldn't the US Treasury rubber stamp a policy that allows them to
print as much greenbacks as they like just so that they could
service their national debt? (for the sake of this argument, let's
assess this simply given your limited intellect and overlook the
fact a protracted government bond is actually mutually beneficial
for both the bond issuer and receiver - in this case, the US
government and the investment banks issuing the bonds - as it
provides a market for the issuer to profit, which in turn, benefits
more than just the receiver)
So what exactly are the factors that curtail the amount of money
being printed in circulation? If, for a moment, you're suggesting
the greenbacks are actually printed in such a callous manner that
it actually doesn't impede anything bar the market demand that
warrants its issue, try telling me the value of the USD actually
doesn't depreciate with respect to other commodities/currencies
which are not pegged to the USD.
If you can't get started on addressing the above, feel free to do
some research at the library...
