Dear Federal Reserve.
Greetings. You have operated under sketchy circumstances for a long time. Lucky for you, macroeconomics is boring enough that 99% of Americans have no idea who you are or what you do. Bringing attention to yourself? Bad idea. If the average American understood fractional reserve banking, they would be very very upset. Oddly enough, I do not have a problem with it, per se. Implementation, sure, concept, no prob.
Try to play junior NSA and it will end with a lot of angry taxpayers. They already do not like you. If they found out about your quasi government, quasi private legal standing, you'll get nationalized. And folks will ask questions you don't want asked.
Kindly back out of the spotlight and keep a very low profile.
