A teacher's salary is capped, structured, and predictable, tied to a pay scale that doesn't move much regardless of how good they get at the job. That's true for most traditional employment, and it's worth being honest about, especially for anyone still in school picturing what income actually looks like once they're out.
Building an app doesn't work inside that same structure. There's no pay scale, no ceiling built into the system itself. One well-built app, sold or generating ongoing revenue, has already outpaced entire traditional careers before, more than once, for people with no more experience than a good idea and the willingness to actually build it.
Describing an app idea in plain English and getting a working version back the same day removes the barrier that used to make this sound absurd for a student to even consider. No computer science degree required. No years of technical training standing between the idea and something real.
This isn't a knock on teachers, or on any traditional career path. It's a reason to know, clearly, that the income ceiling built into a traditional job isn't the only ceiling available anymore. For anyone with a real idea and some spare hours, that ceiling was never actually fixed. It just felt that way because nobody showed you the other door.
