And a snip from medicalecology about Cholera.

There isn't a problem in my mind that corporations exist, and have the resources to develop this kind of research. The problem is when the unimaginable profits generated are then used in dynasty building, instead of diverting those profits to solving the abject poverty of disease caused by infected water supplies caused mostly by missionary activity, and plundering of the resources and peoples of native lands.
Does the generation of wealth mean that only a few individuals have unimaginable power to affect the course of world history, the survival or extinction of whole peoples?
Most of us in this world range from 'uncomfortably poor' to 'comfortably poor' in this mad upside down world we live in. I can't remember the movie, and who was in it, but the story line was that to inherit an unimaginable fortune, the wayward son had to go and spend a fortune. (Parable of the prodigal son).
This was so he learned the 'value of money' before he got hold of the power that goes with wealth.
When Political power can be divorced from wealth, perhaps we might see a more equitable world for everybody.
