Fixing Hubble was one of the most complex operations the Shuttle ever did. Although only the shuttle could do things like repair and retrieval, the large majority of the satellites that ever entered the Shuttle cargo bay were simply launched and released.
More specifically, of the 105 satellites the Shuttle interacted with, only 4 were repaired-and-redeployed (including Hubble) and only 5 were recovered back to Earth.

Do you have cites to support this? It's not consistent with my impression of the expectations for the Shuttle when it first started flying. Your other comments here give the strong impression that you are arguing based on your intuitive knowledge of spaceflight costs that no reasonable person could have thought launching dumb satellites on the Shuttle would have been cost effective. However, I think that's hindsight, and in fact many people at the time expected the Shuttle to cheaply deploy basic satellites, and that this was part of its official mandate. Indeed, Wikipedia says
> the plan was for all future U.S. space launches—space station, Air Force, commercial satellites, and scientific research—to use only the space shuttle. Most other expendable boosters would be phased out.

EDIT: And from another link in this thread (written at the time):
> NASA plans to terminate all throw-away rocket launches as soon as the shuttle is working.

Say what? I didn't know they had interns up there.
There's also "Space Shuttle Decision, 1965-1972 (History of the Space Shuttle, Volume 1", but I think Volume 2 is far more interesting from an engineering point of view.
This isn’t how it was sold to the public.

Thank you. Without the ISS, we wouldn’t have SpaceX.
Manned space flight is known to be way more expensive than cheap, rocket satellite launches. There never was a comparison.
The Shuttle was going to be cheaper than manned rockets, and frankly, probably was. I can't imagine who much it would cost to put up a manned rocket to do some of the retrofitting of Hubble, for example. I don't even think their is proper vehicles for that in existence! So it would be out of the question in terms of cost.
The shuttle did mostly what it was supposed to, it just got old. And there is the space station to do science.
Soyuz + any international heavy launch candidate duplicates the Shuttle’s capabilities at a fraction of the cost.
Thats how we ended up with thee uterly insane SLS, Orion, Gateway architecture.

Also context, consider cost complexity: manned space flight >> space flight >> aerospace >> automotive.
Each increase in risk implies considerably more expense, and the difference between space flight that includes humans, and flight that doesn't is quite massive. They are different programs entirely.
So if you're putting something in space with 'humans going along' - it will always be way more expensive, no matter what.
The shuttle was supposed to be cheaper than multiple manned rockets, but not cheaper than regular satellite launches.
So for putting out complex things like Hubble, or 'fixing it' 'retrofitting' etc. - the Shuttle might make sense.
But it was never going to be cheaper than regular rockets for putting relatively straightforward satellites in space.
