All of those things you've listed as examples should also be managed by someone with a technical understanding of them.

I wouldn't want someone with no understand of the concept of inflation for example in charge of interest rates.

Equally I wouldn't want someone in charge of nuclear weapons that doesn't understand that if you let of a bomb in the next country you'll get covered in your own fallout.

it's harder to micro bullshit (be hands on) than macro (feign competence using "models") bullshit. If you are clueless about infosec or the hardware it relates to (using a computer) why are you a leader in the ministry of said field for a country?
