Short story: two men smugly discuss their work at a facility, where people whose jobs have become obsolete are somehow (drugs maybe?) kept under the illusion that they still are employed and affluent.
Zinger at the end: the two men drive away in what they think is a shining new sportscar. But is revealed to be a pedal driven cart, they themselves have been drugged/hypnotized to believe they are better off than they are.
ETA: I read it in an old anthology, don’t remember title.
