Indeed, "dumping raises into savings" was one of the smartest things I ever did, financially. When I moved from working from a university to working at a mid-sized corporation, I got roughly a 25% pay bump. Every single dollar of that went into savings (fully funding the 401(k) and Employee Stock Purchase Plan, etc.).
This did a couple of things... it kept a lid on living expenses because there was no additional cash, but it also provided an easy way for me to raise my savings every year without having to make too many conscious choices, just by moving every pay raise into savings.
