Maybe you don't believe that opportunity cost is a real thing, or that it applies to real life. Or maybe you simply don't fully understand what it means. Therefore, I refer you to an article describing what it is, and it's utility when figuring out whether you should hire a housekeeper (and other similar decisions).
Cue all my readers who don't know anything about economics singing in unison about:
- How I am wrong.
- How only rich assholes hire people to do their grocery shopping
- How only a bourgeois jerk would think this is a concept worth considering (the rest of us have to WORK for a living, dammit!)
- How economic theory has no application to real life
- How I make a salary therefore this does not apply to me
