That's categorically false, unless you have very narrow definitions of entrepreneur and craftsman. It seems like in practice, the line gets pretty blurry. Aren't all entrepreneurs craftsmen in some regard (if not with respect to their product, then to customer experience, process, or something else)?
For instance, Honoré le Blanc, Eli Whitney, et al pioneered the concept of interchangeable parts for business purposes. Were these guys businessmen or craftsmen? On the one hand, they eliminated a lot of the art of gunmaking, but on the other hand, they made more reliable guns.
That said, one cannot completely dismiss "business" as a skill. Management, business direction, and market "intuition" are all skills, and when properly used, they give the necessary direction to the true creators: engineers, craftsmen, etc to allow them to excel.
What would Woz be without Jobs?
Entrepreneurship is directly related to innovation. Innovation does not have to mean inventing the light bulb. It can also mean coming up with new ways to do things (e.g. Southwest Airlines). Entrepreneurship is an integral part of what makes capitalism work.
Additionally, just because you're a craftsman doesn't mean you can never be a businessman also. Any individual craftsman that wants to make any money from their creations will have to at some point become involved in business. Even if you're just selling your new technology to a big corporation and not starting your own company, you're still having to make a sale (which I'm pretty sure would go under the business category).
Those are just as important to economic progress as the engineer type. Assuming there is a real global shortage of a given type of skill and an excess of others, we all benefit if appropriate reallocation is inspired.
Dale Carnegie = Marketeer
-He authored the bestseller: "How to Win Friends and Influence People". The book continues to sell today even though it was first published in 1934. I'd recommend it even to non-Marketeers.
Andrew Carnegie = Business Guy
-He's remembered as a Business guy for doing titanic mergers and acquisitions in the Steel industry. However he did not come from a wealthy family and started his first steel company from the ground up.
