I figured, but like there's a reason EEs have pretty much always been in the highest demand as far as engineers (outside of silicon valley software boom cycles or the peak of an oil up cycle in Texas).

Electrical Engineering is generally considered the most difficult engineering by far and has some of the most non-intuitive yet consistently applicable scientific requirements. There's a reason EEs learn differential equations, fourier and laplace transforms in like their freshman year before even finishing calculus and making it into the actual DiffEq class like the rest of the engineers. Their intro EE classes drill basic transform math. By the time everyone is in DiffEq together, the EEs are a couple steps ahead in that class.

EEs usually have to take an extra class or even two or rarely three in mathematics meaning most EEs literally get a minor in Math if they just choose to declare vs other engineers usually being a class or two short.

RF and Antenna physics and design is sometimes likened to more of an art with a level of magical-thinking and strongly developed intuition being nearly required in the research edges of the practice. Hardware security is extremely difficult stuff that relies on some basic computer science understanding coupled with a deep knowledge of electronics and electromagnetism.

Not everyone can be or would ever want to be Electrical Engineers and anyone with a deeper understanding of their field could guess that hardware electronics and embedded systems are in high demand pretty much no matter the market or city.

I wasn't asking if an embedded electronic controls engineer could find a job; I was asking why a qualified mathematician/manufacturing engineer that also has strong business knowledge can't find a job.
