I don't think you need to be a master to get more money. What I have noticed as a hiring manager/tech lead is candidates/team members fall into either asking for more money or not.
I have guys on my team who if they asked for money I could easily add 20 - 50k to their salary. But they don't, they also don't shop themselves about. They're low risk of jumping ship and if they do, I can offer them a huge amount to stay or with the savings I have made over the years I can replace them at market rates, suffer the disruption of introducing a new team member and still be ahead.
I luckily learnt early on the best thing to do for your career is just ask for more money. Every 6 months I ask for a pay rise. I don't always get it and if I don't I ask 'what do I need to do get more money'. Your boss should be able to tell you what you need to do to justify another 10 - 20k to your salary
