Why is there a lack of service businesses in the wizarding world?

Following up on our earlier episode about magical businesses, our technical director, Emma Nicholson, joins us to continue the conversation. Perhaps there aren't many businesses that provide services, as opposed to goods, to wizards because people with magical skills should be able to easily do household tasks for themselves. Not being able to do so is seen as shameful. Consider the characters who perform manual labor or do maintenance work - house-elves, Squibs like Filch, low-level Ministry employee Reg Cattermole.

What about entertainers, such as magical athletes and musicians? Is that kind of physical work different? Previous guest David Martin also wrote in wondering about what is considered a service business. Gringotts? The Knight Bus? St. Mungo's Hospital? Niche specialized skills or blended businesses that provide a product as well as a service, like newspapers or wedding marquee rentals, seem to be different than straightforward services. What does this say about the significance of tangible objects wizards can own?

Why don't wizards open businesses to provide services to Muggles, secretly using magic to easily make or fix things? Why is any wizard poor when there's a whole untapped market of Muggles who would have more need of their skills? The International Statute of Secrecy and resulting segregation between wizards and Muggles may stop anyone from crossing that line. Magic leaves a trace, and magical repairs may not always work exactly as intended or may be suspiciously effective. The risks may just not be worth it to most people.
