Since the world leaders are not so interested in the "interest" issue and do not care to ponder upon the ill consequences and for the future of a debt free society. How long does it take for a system to show its colours?

And are there ways to ridicule/over smart this system without using illegal or provocative measures ?

It is true that sometimes it has to get worse before it gets better. Any system build on falsehood will eventually self-destruct. We should not waste our energy trying to hasten the demise, but work hard on finding alternatives to replace it. Rightly though, the dissemination of information about the pitfalls of the prevalent system and the alternatives is a key ingredient for change.
