Your attitude seems common, but I'm quite curious just how common it is.

Personally I totally happy with my current income and don't have any real interest in making more. I can pay my bills, buy anything that catches my eye, max out my 401k, travel to visit family. I don't turn down raises or bonuses, it is nice to have a little bit extra in case of emergencies. But an extra dollar doesn't mean much compared to the personal satisfaction of working on good projects.
