Doesn't necessarily have to be business owner with employees. Could be like one person self employed, maybe with a brother or something.

The last plumber I hired was two brothers, who do good work, charge like $100+/hr on labor, but are considered self employed and thus don't show up in that dataset.

If it’s both brothers for that hourly rate, then that is only $50 an hour; and probably also has to cover expenses like business insurance, car insurance, gas, tools/equipment, car and equipment maintenance, certifications and contractors licenses, etc, etc.

And I’d bet their rate even has to take into account the time in their “off” hours when they are writing estimates, invoicing, communicating with clients, marketing, and so forth.

They don’t just clock out when they finish fixing your plumbing. Even at $100 each, it’s not pure profit. Running the business probably eats into a big chunk of their hourly rate.
