[Star Trek] Why is almost everyone on my ship a commissioned officer? Why are there so few enlisted on my vessel?

I joined Starfleet to get a good education and see the quadrant. Whenever there's an away team, only the officers get picked. Even that Lt. Barclay gets to go, and I'm stuck here cleaning plasma injectors. What gives?

Away missions tend to be of great importance, so it's only reasonable that the most experienced and trained crew members are the ones who go. 

And not everyone on your ship is ao officer. Only 120 are. The other 1530 are enlisted or civilian reps (not including family members).
