As I have mentioned many times, I watch a lot of documentaries. There is so much about the world that does not make it past the mainstream media filters. The internet is a blessing in that regard because it makes alternative information more accessible to the general public. Pigtails in Paint is a case in point.
I came across a short video produced in 2012 of a speech by 12-year-old Victoria Grant about the nature of the banking system and how money works. Naturally, this is a well-rehearsed speech but I think the point is that the key concept is simple enough to be understood by most reasonably educated young people. Efforts by economists to make certain aspects of this system seem complex when they are not is really a cynical diversion to keep the public from realizing just how obviously unjust it is. Grant has followed up on this theme in subsequent years.
