This idea is sometimes made quite overt. So when Alan Greenspan was testifying before Congress in 1997 on the marvels of the economy he was running, he said straight out that one of the bases for its economic success was imposing what he called greater worker insecurity. If workers are more insecure, thats very healthy for the society, because if workers are insecure they wont ask for wages, they wont go on strike, they wont call for benefits; theyll serve the masters gladly and passively. And thats optimal for corporations economic health. At the time, everyone regarded Greenspans comment as very reasonable, judging by the lack of reaction and the great acclaim he enjoyed. Well, transfer that to the universities: how do you ensure greater worker insecurity? Crucially, by not guaranteeing employment, by keeping people hanging on a limb than can be sawed off at any time, so that theyd better shut up, take tiny salaries, and do their work; and if they get the gift of being allowed to serve under miserable conditions for another year, they should welcome it and not ask for any more. Thats the way you keep societies efficient and healthy from the point of view of the corporations. And as universities move towards a corporate business model, precarity is exactly what is being imposed. And well see more and more of it.

Alan pretty much as said such but not in the exact words I posted.
