If she doesn't want to expand, she can just pay herself a higher wage for doing such a good job. Profit is superfluous for her - it's probably just a tax thing in her case, where she gets a better tax deal if she pays herself with profits instead of wages.

Her "profit" is literally just the money she isn't paying herself in wages. That's what all profit is, hence, profit is theft. The fact that she is sort of stealing from herself for tax reasons just highlights how unfair tax law is imo
