Money is unavoidable, so if you're going to be unhappy about earning it, you're going to have an unhappy life no matter what.
I kind of doubt money is the issue...you might just be looking for inspiration.
Maybe look into the nonprofit world. These are organizations that stand for something, and most are in desperate need of technical talent. You won't make as much money but if you can work for a cause you believe in, you might feel your work is more worthwhile.
