You have no idea what you are talking about. How exactly does GS manipulate the markets to its will? You'd think their balance sheet would look better if that was case..
Goldman Sachs did not manipulate LIBOR because it's not even one of the banks that is asked for LIBOR submissions (they were an investment bank, not a commercial bank).
I'm all for bashing banks when it's appropriate, but it's our obligation to get the facts straight first.
At minimum, GS has done this in the past via political back-patting. Any other means would not surprise me, although to be honest I could care less if I am right/wrong about this particular case. :)
They rig the ratings agencies and libor[0].
