I just finished the book I posted about 3 posts up ("Dollarocracy" by John Nichols & Robert W. McChesney) a few days ago and if I could, I would make that book compulsory reading for everyone living in America.
It's a very eye-opening description of how the media, money and politics all mixed together has completely corrupted democracy to serve the interests of the wealthiest. (Hint: A country must have a strong independent media who will investigate and report on politicians and their platforms so that citizens can cast informed votes, as opposed to the corporate-owned propaganda "news channels" the United States has that don't investigate, but simply report press-releases put out by whatever political party they favour and present it as "news". In other words, instead of keeping politicians honest and debunking their lies, the media helps them spread whatever spin/propaganda they put out.)
If you want to know why the USA only came in 25th on the list of "best functioning democracies" in the world in 2018 - and why it's not even listed as a "full democracy" - then read that book.
I'm currently reading "Columbine" by Dave Cullen.
