Generalising a bit, it seems to me that in Asia a lot of political leaders come from engineering, whereas in the US and Europe many come from the humanities, especially law.
Margaret Thatcher (somewhat controversial, I know) had a 2nd-class BS Honours in Chemistry from Oxford, and apparently the first UK Prime Minister with a science degree. [source: Wikipedia]

It's been a good-enough approximation for most of history, even though in practice it's completely wrong.
Politics is badly in need of a Copernican revolution which puts the physical world at the centre of politics, not the periphery.
I wish we were lucky enough to have a leader with a degree. The current Swedish prime minister worked as a welder and dropped out half way to his degree in social work.
