Star Trek is, and always has been, an allegory for our present lives. Otherwise, you wouldn't have the numerous episodes that deal with modern day topics such as abortion, cold war, the holocaust, losing a parent, etc. in a futuristic way.
Obviously it is and has been an allegory for our lives today. But that doesn't mean it's exactly the same. In fact, it's ridiculous to accept that. In the Federation they've essentially conquered greed and poverty (to various degrees, depending upon the episode). Tell me we've conquered that today! My point is that these people are driven by different motivations, as Timo stated. I felt they spent a little too much time on the whole competition bit for promotion. Based on what we've already seen across all of the previous seasons, I don't see evidence of it being that intensely competitive.
