This is the problem, because you know what else is controlled by the market? Your employment. I fully encourage going on strike if asked to make surveillance tech, but you will be fired for it. Then some other firm will be hired, and, oh well.

If "the market" controls democracy, to the extent that the "democratic" government demands surveillance tech because someone on the market wants to sell it, that's the problem to be solved, not a shortage of research scientists martyring their careers for no effective gain against the larger social pathologies.
