The only advantage is that if the company is more efficient they'll be less likely to fire you because the business is failing. They'll just be firing you to eliminate a cost.
Choosing to clean your own house instead of hiring a house cleaner, cooking your own food, doing your own landscaping, driving your own car, all of these are “classifying humans as a cost”.
I probably could afford a maid and landscaper, but I don’t because I would rather keep the money. When an employer does that, it is somehow different.
