If you are a programmer and needs to solve issues and bugs... you can't just cut and paste... you need to understand the program, the flow of information and debug the issue. But sadly a lot of half passed six 'programmers' out there that also just cut and paste without understanding the underlying process and when issues cropped up and they could not solved it, they just shift company.

Anyway you need to move up the job chain. There is always a ceiling pay for certain jobs. Move up the job market. Don't get stuck with the same job title doing the same thing again and again and expect the salary to increased exponentially. Move up to manage people.

Yup we still have lots of low value-added jobs in the market that has a ceiling to their salaries. These jobs are usually entry levels and usually get you started to gain experience and should be considered as a stepping stone to move on to other jobs but sometimes the process is quite complicated, it ended up being the main job with very little progress. That's when the person got stuck with the stagnant job and salary.
