Of course you're not going to get a huge raise. Only three ways that happens:

1. You directly generate money for the company, as in, you bring new revenue. Most employees are cost centers.
2. You get a huge promotion, and even then, you're not likely getting a 20%+ bump.
3. GET ANOTHER JOB.

#3 is well-known and obvious to those of us in tech. I often forget that non-techs and young people may not have got the memo. My last job hops have bumped me 30% and 90%.

Non-tech example: My friend took an oil change job when we moved here. That was well below his skillset. He kept proving his skills, improving his skills, moving up a bit and moving on. Now he's at $120,000 and is the service manager for the largest car dealer chain in the area.

And no, employers generally do not expect our lifelong loyalty. They talk like that, because it would be stupid to talk otherwise. I've answered "Where do you see yourself in 5 years?", with, "Let me dig in and see how it goes! I may move on at the 5-year mark to keep my skills growing and fresh."

HR didn't bat an eye. "Well, we hope you enjoy your 5-years here!"

Keep your resume polished and move on!
