I dont need to skim through this. I have a very solid understanding of the Federal Reserve system already.
You seem to be conveniently unaware that the Fed rebates almost all interest payed to it by the government, so net interest expense paid towards the Fed is almost 0. It is actually a beneficial arrangement to have the Fed maintain a significant bond portfolio, as we would be paying that interest to someone else anyway. This arrangement lessens servicing costs significantly.
Read an Econ text book instead of getting your information from pseudointellectual bloggers.
is the fed a government agency or owned by private banks?
