I wish technology solved people issues. It seems to just reveal them.

I'd rank the Voyager programs way up there for space programs.
The solar observatory program has day to day benefit in being able to see large solar storms which can screw us over.
If we want to get into ROI of gov programs, there are a few I could list that had a huge initial ROI. The first few years when either starting from nothing or correcting major issues there is large benefit. Then they reach a point where the big returns have been reaped and they become pork or enforcement arms for pet policies.
But don't forget that something is probably learned with each of those repair shuttle missions; there's no such thing as bad experience. Maybe some critical knowledge was gained through those missions that might not have been learned had there not been a Hubble to serve as an excuse to go out there.
