At this point I would just like to reformulate my original thesis.
3,000,000,000 people could achieve anything they set themselves to do, without compromising their free will.
The rich countries could solve all economic problems and still make a profit.
However, before any of that became possible, they (including you and me) need to have the will.
The longest and hardest journey must of necessity begin with a single step.
This 'thread' has convinced me that that won't be happening soon.
Arrogant beggar aren't I?
