Point being, not only do the middle class provide universities and health-care by paying taxes for them, they make up a large portion of the actual professional labor force at those institutions.
I'm very, very left-wing, but having newspapers print long articles more-or-less pointing and laughing at any of the workers who actually keep whole countries running is pretty goddamn insulting, and that includes when they label those workers "middle class" or "hipsters".
Dignity in labor applies to the white-collared, too.
Although admittedly it has now backfired, as it's now easier to have children on welfare than it is for many working would-be parents.
The working class WILL stop working and in the very near future, as basic jobs such as checkout staff, or taxis, become automated. It's an impending crisis.
My colleagues might manage a token one day strike now and again, but basically that is your lot. What is termed 'action short of a strike' can actually be more effective in certain circumstances. Cutting off the flow of data really bothers the management but the everyday work of the institution continues; students continue to be taught, to have work marked and to receive feedback designed to improve their understanding of the material.
