I think it is significantly more difficult to find programmers with domain expertise in the kinds of applications C++ is often used for than the language itself. There are quite a large number of good C++ programmers who have never worked anywhere close to the metal, OS, high-performance, etc, and those skills are often more difficult to learn and come by than the language.

A large amount of C++ development is still focused on enterprise and UI apps, even though one could argue that it is not the best language for that purpose.
