Here's two somewhat lengthy videos of Marc Faber. I suggest you watch both and see what one man thinks about the past and future. While I think it likely his prediction central banks will keep printing it is not assured.
The second video is a debate between him and Arthur Kroeber of Gavekal Dragonomics regarding the 'bubble' in China. One item to note is how many people in the room think China will overheat.
