I can't recommend the link you gave. It is a contrived, cobbled together piece which includes some comments supposedly from from Pace University economist Joe Solerno*, I suppose in an attempt to give it some legitimacy . Unfortunately it contains many statements, that while they may have been true, or at least partially true, at some point in the history of the Fed, are certainly not true today. It is best described as a piece of dog shit. It calls into question the legitimacy of that thing called the " Mises Institute." This 'Institute' has the ear marks of something originating in Russian Hack shops or an Alabam swamp. I'd check it out thoroughly if I were you. Especially the source of the funding (which mark my words, no donors names will be forth coming)for this "magnolia Ave." Alabama outfit. The great micro economist Ludwig von Mises would turn over in his grave if he knew his name was associated with this pile of steaming horse dung!!!
The Wapschot book is readable by the non-economist if you have an interest in moving forward in time into the mid twentieth Century and well beyond the Austrian School, which became mired in microeconomics. It's "Keynes Hayek: The Clash that Defined Modern Economics." That could be a good jumping off place to start late twentieth century and early twenty-first century critiques, such as Quiggin's "Zombie Economics." Quiggin's book remains a seminal critique of Supply Side Economics and crops up often on Graduate level Economics Reading Lists.

*Joseph Solerno is a legitimate, Rutgers trained, Austrian School, radical, anarcho-capitalist Economist. He might be able to offer a clue, in fact he could be one of those responsible for, the misappropriation of the tern 'libertarian' in the U.S.
Rutgers of 50 years ago was well known hot bed of radical economics. Left and Right. It is not unusual to find some extremely bright and capable Rutgers trained economists relegated to back waters like Pace University. Their thinking is just too far from mainstream to find wide acceptance.
