Coding isn't just left-brained. Efficiency comes through seeing patterns and developing novel solutions. Coding uses just as much Te as it does Ne. If it didn't, then why would the hiring processes at places like Google or Amazon be so rigorous? It's because they need to see that you can think both linearly and nonlinearly.
Efficiency never goes unrewarded since that's the whole point of checking code. If you can solve a problem in 10 lines which takes another person 40 lines, then you won't be unrewarded for that unless the company is masochistic or unless your solution is far too narrow.
What about legal work? Is it to "left-brained"? Any lucrative career will require a substantiate amount of left-brainedness since otherwise it would be unreliable or unstructured. However, those same careers require nonlinear thinking and creativity since otherwise anyone would be able to do them.
Seems like you're against almost any job that pays well. I can only say that this is your own fault since you aren't willing to adapt to the market like others do.
I agree that SEIs have it rough compared to other types that find these careers more palatable but that doesn't excuse you from pulling yourself together and getting something done for the sake of money. It's something that everyone has to do.
