All jokes aside, there are times when it seems like people from the Trek future practically go out of their way to be patronizing toward those they find from "our" present. About the only two exceptions that I can think of are Edith Keeler (whom Kirk and Spock both acknowledge as forward-thinking) and Gillian Taylor (of whom we learn nothing beyond joining a science vessel).
For what it's worth, I've felt that whatever we were supposed to take away from Star Trek was meant to be applied to our world rather than making us wish we lived there. After all, that's the only thing that can really happen.
Also, I've come to the realization that we know very little about life in the Federation, and what little we see is looked at through the lens of Starfleet. We're told a lot, but we don't see much of it. There too, there is a patronizing attitude toward civilians from the Starfleet point of view.
