In the fire service when the firefighters are not performing it is the Lieutenants and Captains fault. If the line officers suck it is the fault of the Battalion Chiefs fault and the fault continues up to the chief. The same is true for the civilian world. This is called the chain of suck. 

Hold your people accountable set the example and provide expectations.

Don't allow your people to only point out problems. Set a rule that no employee can point out problems or complain if they don't offer solutions. Your people must have the confidence to make decisions and offer solutions.  Support their ideas and encourage them to speak up.

Just because some people are not into the job like you are does not make them bad employees. Some don't eat and breath the job like you are. Don't compare someone else to your views. Look at their performance on the job, you will find they are every bit as good as you.

SUCK LESS DO BETTER
