What economic incentives would lead the mass media to behave in this manner, assuming that you agree with Ehrenreich?

Ehrenreich notes an apparent need for "approvai" from the worker's supervisor.
She also notes that mass media images are decidedly negative (or absent) regarding low wage

that this is an accurate portrayal of mass media imagery (verify by noting TV or magazine
images)? What economic incentives would lead the mass media to behave in this manner,
assuming that you agree with Ehrenreich?
