The best way to make more money is to get a new job. Employers take advantage of the fact that getting a new job takes work and can be uncomfortable, and a lot of workers avoid having to deal with this and accept a stagnant wage. At my previous employer, I was hiring new staff again $10K-$15K/yr more than staff that had Been there 5 years. My advice to every new grad was to work there for 2 years for the experience then find something else. If you liked it enough to come back, after having 3 total years of experience you could easily get $10K more than you made before
