I'm sure there's far easier targets than the Federal Reserve if you're concerned about mother nature, giant boondoggles like the NBN, the white elephant desalination plants, the Collins submarines, and then of course there's government departments.
The Federal Reserve does an excellent job of regulating the world economy, and just you before you mention the GFC, the Fed saw it coming but couldn't stop it because of all the sheep piling into risky assets.
Maybe you should check out the environmental damage done by goldminers, that'd be a good start.
