It absolutely does benefit me to save time, because writing css by hand is one of the most soul-crushingly boring tasks imaginable. Sure my employer also benefits, but that's only if I use that saved time to write more code. Maybe I use the extra time to walk my dog.

I have a fixed number of working hours in a week regardless of my efficiency, so even if I manage to make myself efficient, I don't reap the benefits.
