In my experience, front-end projects always seem to get more attention and visibility from product teams, and the business in general. This seems to happen even when it’s a nascent product that doesn’t make any money yet, and older, more boring systems responsible for large percentages of company revenue often get ignored. I’m not sure if this is related to pay in any way, but it definitely seems like the visibility of front-end apps, and being able to showcase them to wider audiences, doesn’t hurt.
