And that's a really common case.
It is absolutely true that you need both technical and non-technical people to make a business work. There are lots of jobs to be done, hats to be worn, and they are all valuable - many are necessary.
The issue is that our society and economy massively overvalues two roles in particular: those who bring the capital and those who carry the title executive. It's not that those roles don't contribute, they do. But they currently get the vast majority of the generated wealth, credit, and recognition (which then translates into more opportunities to access more capital and thus into an exponential feedback loop).
