"You just keep telling yourself that..."
I'll be over here. The greater expressiveness of C++ means that optimization effort can be, and routinely is, captured in libraries where it benefits every user. Because optimization effort is amortized over all users, more attention can be devoted to it -- and, again, routinely is.
Powerful libraries that can eke out machine potentialities without compromise and deliver them to many users, to compose with other powerful libraries, make a language fast and quick to code in.
C++ isn't the only language good for capturing optimization in libraries. Rust is good and getting better fast. I don't know about others. D, probably.
The MLs and Haskell could be good in this way if they were not saddled with obligate GC.
