But only within a certain design, so one can sometimes get as good or better quality with a different design. Using the scope mentioned above it's a fixed 4x model, about as simple as one can get, and since range is limited and recoil isn't an issue a scope based upon those as design criteria for a centerfire can do well on rimfire.
In binoculars the expensive stuff is typically roof prism models from Europe, but well executed simpler porro prism models are the reference standard at places like Better View Desired and among people who point binoculars to stars, binoculars that typically cost a lot, lot less. Stars are unforgiving test targets.
Another example is looking at old models from Tssco (a company that has deservedly bad reputation now) as they had some excellent binoculars with high resolution, but the coatings back then aren't nearly as good as current models. Still, it seems that the polish was better in ye olden days on many optics, even if the coatings and designs are dated. I also have an old Tasco 60mm objective from a 'department store scope' that someone gave me that star tests very well, and another old 50mm Tasco that someone gave me. After adjusting the air space a bit I've been able to see shadows from it's moons moving across Jupiter, something that few fancy, really expensive spotting scopes can do as they typically can't be used up to 120x.
In summary, yes, one pays for optical quality, but one can also do as well with simpler designs that don't require higher tolerances to begin with.
I essentially only use my 8x42's on stars. Seeing jupiter's moons through a low-power field is amazing, among other things.
