I think a lot of your points are completely valid and it’s easy to see that most of your frustration is really the industry, and not the UX work itself. Here is my perspective from another Country.

As a Senior Developer in North America (Canada), I’ve observed that UX is a role that many companies don’t fully understand, unfortunately. UI is not UX, and Graphic Design isn’t necessarily UI, but there is a bit of overlap between them all.

Wearing multiple hats is what companies expect for many positions these days, but I can tell you what I think is relevant; anything more than the following is asking too much. Knowing a little bit of project management-like work is a good trait because UX should be at the core of good product development and not an afterthought, so we should be thinking of UX during the entire project lifecycle. Some data knowledge may also be good for tracking user analytics or other data collected for UX purposes, but also for data layout strategy. Knowledge of UI coding is good, because when a developer is asked to do custom UI, implementing ‘X’ can be 5x–10x as much work as implementing ‘Y’ which might work 90% the same and look 70–80% as good as ‘X’. It would be nice if designers know what they’re asking for. With all of that said, I’d only expect most of the above from Senior or Lead UX roles.

Those UX wages sound like something hard to get motivated about. I never talk about salary with colleagues, but I’d have guessed them to be in the same range as a Junior to Intermediate Developer, depending on experience. A search on PayScale in Canada would show my guess isn’t too far off. I have met some awesome UX designers, but unfortunately not all software companies really value the role as much as they should. Many companies don’t even think they need one full-time – whether or not they actually do, really depends.

If it’s something you love doing, hopefully you can find a way to make a livable wage off doing something you really enjoy. If you’re ready to walk away from it entirely, maybe it’s not your true calling. Good luck in your career, whatever you do.
