I laugh at people bitching about their pay. Move. On. Why would the company suddenly throw you a 20% raise!? Out of the goodness of their heart?
My last 3 jobs (top pay): $14 -> $22 -> $39. At this point I could probably jump ship for more but I'm quite content to retire out of this place.
Stay put 3-5 years, gain experience, jump. When we moved here my buddy took a job at an oil change place, barely above min wage and far below his skillset. Kept job hopping and now he's making $120K+.
