SE is different because those other professions generally aren't creating anything. If SE had a program where it just writes the code for you, then we wouldn't have to test them, just like an MBA can work off existing Excel sheets because what matters is the output of that application. Most new code and bug fixes require extremely detailed abstract knowledge that (so far) hasn't been able to be commoditized into an application. The next few years may be a game changer for that though.
I don't agree that those other professions aren't creative. If anything, the ambiguity behind what constitutes a successful brand design or convincing a client to buy your product seems to require more abstract knowledge to me (as a software engineer) than the ability to read and implement syntax.
the vast majority of people who work in offices just push papers, go to meetings and other mindless bs. the people who build brands are higher level managers/ivy-league over-achievers. sales people are hired or retained based on talent, getting a very low base salary and high commission. writing code is way more than reading and implementing syntax, it's actually making the design work or solving very tricky bugs. People with bare-minimum degrees and no demonstrable acumen are useless. take any given tech idea you want, it doesn't "just work", the devil is in the details.
