Who Serves Best

Politicians have the potential to serve best, but usually end up serving greedy capitalists.
Scientists have great potential, but usually end up working for brutes and are then used to create horrible weapons.
Doctors are great in every community, they could well be the best.
Teachers, some of them are very influential on their students, but a lot of them are not.
Soldiers, I see them as a tool used to serve imperialists interests (thinking of America).

From one perspective the Scientist serves best, even though he is used to create very dangerous weapons which is horrible these weapons can be used to bully other countries around and to suit their own interests.
