The problem Dr. Foley, is the administration, allocation and distribution of societal resources. In other words, politics, the means we use to manage societal resources. In America we have some say in choosing our political leaders, in other countries, people have little to say if anything. Politics invariably means making choices, for the betterment of all or for the betterment of the fortunate few. Politics may or may not be a zero sum game but if societal resources are limited, it rapidly moves in that direction. The value systems employed making political choices range from outright theft and corruption to heroic self sacrifice, but when all is said and done it still remains a matter of choices. Science truly has advanced the standard and quality or human life but it has also delivered the means for its self extermination. As the former Pope of the Catholic Church said, there is no commodity that is more easily found anywhere in the world other than weapons of war and killing. Whatever claims science and scientists may have had to moral scruples, I suggest to you they have been tarnished irrevocably, some would say renounced, with the development of nuclear weapons. Today the best we can hope for is that world political leadership will be able to check and control those people and nations that have them, courtesy of their scientists.
I think it is admirable that you see yourself as willing to devote your energy, skills and education to the betterment of the human condition. It speaks very highly of you; however I am certain you would agree with me that not all scientists, certainly not those in the pay of the armaments and weapons industries would agree with you.
In any case keep the faith.
