I've begun treating and thinking of myself as a small business, and the mindset has offered me a bit of clarity and empowerment. Let me explain.
American culture has conflated the value a person offers a job and the value a job offers a person. The expectation seems now that people need to be grateful for the opportunity of a paycheck, instead of a company being grateful for employees producing profits.
Each and every one of us is a business, and the product we sell is our labor. We sell our labor, and companies buy that labor, and convert it into profit. Don't trick yourself into diminishing the value of your product and don't sell it for cheap.
That's simply bad business sense.
