More like "A restaurant that makes 50,000 per month in profit isn't profitable if the person who made it is Bill Gates, if Bill Gates has to work as the maitre d'hotel for 40 hours a week, and that's the only way the restaurant can get any foot traffic". And, actually, that seems like a reasonable analysis.
You seem determined to not look for similarities, so, to spell it out, the "is Bill Gates" translates as "is willing to work for less than market rate" (presumably in the expectation of upside). If your work isn't so exciting that you can get people at less than market rate, wonderful, but I imagine most isn't.
