Personal experience - in every single work I've done (roughly 10 customers/employers, perm+consultant) in 3 different countries, there was/is always room to grab more responsibility, more tasks etc. State of IT usually just a variation of a term MESS, with some technical debt here and there, everywhere. You work harder, solve more, take more responsibility and your career progresses along (or you go to place where it does faster).
But with this might also come 9-10 hours at work instead of 8 (plus lunch), company phone which is there just to remind you of the work when you're not in, maybe more weekends screwed up and so on. Even in otherwise very work/life balance oriented employers.
Want another advice? When having a formal talk with your boss, tell him you want a raise, but you don't want it for free, rather bringing added value. Define clear terms what is expected from you to get there, fulfill them and watch the magic happen :)
