"…medical problems have an important class-political dimension. Given the wider realities of power, it is easier to spend billions looking for a cure than to challenge the big economic interests that are part of the cause. The tendency to define medical problems as separate from politico-economic power is itself a profound concession to politico-economic power. Scientists may seem themselves as independent, dispassionate, truth seekers free from vested interests. But in reality, they are tied by economic necessity to the corporations, government agencies, and academic institutes that pay their salaries and establish the conditions of their labor."
