It gets a lot easier when your team mates are at least working as hard as you are, or if they're on the same page knowledge- or skill-wise.
this single-minded expectation makes sense if all of you sat down early in the project and agreed to share this perspective. let's suppose you also level-headedly discussed how to handle deviations from this expectation, but somewhere in the implementation things went awry and now you feel like your trust in humanity is gone.
it would also make sense if you have a broad definition of what it means to "work hard" and "be capable", and, again, your sense of trust has been substantially undermined.
otherwise, it sounds like you only respect people exactly like you. i don't think that makes for a strong team.
