Middle class people can't distinguish their work from their identity. They seek a perfect harmony of purpose and output, in order to be the perfect servant. They need to sustain this for a lifetime, so their pleasure must come from the work (or they can supplement this with a hobby that is extremely job-shaped.)

If they fail at this, they will be ejected from the middle class, and their children will not be properly educated, therefore never beginning the middle class journey. If you're born poor, it's easy to stay poor all your life; if you're born rich, it's easy to stay rich all your life; the middle class is the class that has to reproduce itself every generation and sustain itself by constant service and sublimation of their desires and dreams. That's why they're simultaneously overpaid and overtaxed - just to keep them caged and desperate, a layoff away from a family annihilation. Loyal to death.

Fear of Falling by Barbara Ehrenreich is a good book about this.

This essay is pompous. Just say: I'm afraid my job is going to leave me, and it makes me feel insecure. Maybe sympathize a little when all of the storefronts on Main Street in some small town are empty after the dog food plant got obsoleted by Chinese imports, instead of telling them they should learn to code like you and to move to where the jobs are.
