Lots of code is valuable to society. Find a product you believe in more if that's the problem. And a lot of software is very valuable but taken for granted.

To pick an arbitrary example, word processing removed all sorts of even less "valuable" work from the world: mailing thing around, extra printing, photocopying, physical filing, transcription services, and all sorts of related rote secretarial duties. Those jobs are gone and people do other things now... maybe they work in healthcare.
