bottom line is nobody can do anything about it and the banks know it.
Unlike the US central bank, ours is an independent body, but the banks are wielding more and more power. Supposedly this rate cut was made so big because the reserve bank expects the banks not to pass on the full cut, but are hoping they pass on enough of the cut to stimulate consumer spending.
So as media becomes more concentrated in it's ownership, and thus political influence through corporate progonda increases, so to does the influence of the private banks on the countries economic decisions.
We are still a long way behind the US, but big business is having more and more influence on the running of the country.
Isnt greed a wonderful thing?
