I don't understand - are you suggesting the only way to know you could have done something better, is to see someone else doing the same thing for comparison? That's certainly one way. Others include... all the ways you evaluate the execution of a company or project, when you don't have a direct competitor to compare it with, no?
Maybe you would agree with the statement "reality is broken"? I certainly don't think it's meaningful.
The unfortunate associations of wanting society to "execute better" (i.e. the merger of industry and the state found under fascism) just underline the fact that applying performance measurements to human life/social phenomena is misguided. We don't all agree on the purpose of life or the nature of happiness, nor should we.
