Just because a profession is challenging or time-consuming does not mean the pay will be commensurate. Those little Wordpress sites are often responsible for significant amounts of small business revenue and the people who keep them running smoothly are paid accordingly.

If you want to get paid more, find a position where your work has a direct and measurable impact on revenue or profit and your compensation will flourish. And if you're already doing that without the pay, then it's time to find a new employer.

It depends on where you are working and the industry you are working on. But if you are doing all of that, and not pay over 50k, it sounds like you are underpaid. The two factors that can lower salaries are lack of exposure to cs fundamentals and theory (usually because you don't have a degree), and working in a non-tech town where they don't pay as much.

If there is one thing i learned in life, there is only little correlation between how much you are paid and how hard your job is.
