IME development resources will always expand to the available budget and time anyway, the programming language or programmer skills really don't matter much.

Also, whether C is actually more or less "productive" than other languages for specific tasks isn't all that clear either. For the things I pick C for (for instance cross-platform libraries sitting between OS APIs and user code, and home computer emulators), it is also the most productive option (in the sense that higher level programming languages wouldn't make me more productive, because all that's needed for this type of stuff is functions, structs, loops, conditionals and a handful of math operators - and all those things are in C). High level features like automatic memory management don't make much sense when there's hardly any heap memory to be managed, and a rich stdlib also isn't needed when all you do is number crunching and bit twiddling.
