Decentralization by means of sensible Agorism is in my opinion the way to go : by giving individuals at the bottom end a completely decentralized means to freely trade amongst themselves without having to resort to centralized entities funding them, they will be inspired to enhance their quality of life by being productive, thus restarting a true free trade economy that works from the bottom up, as opposed to the top-down controlled system we are currently suffering.

I am positive that it is possible to achieve this by means of the tech now at our disposal, allowing humankind to gently ease over time into a new era of peace and prosperity created by free spirits. There may be less peaceful ways of doing this, but non as effective over the long term.
