Earlier quoted context omitted.
"I am positing perhaps they are a democracy." Then maybe take a closer look into how their system works. Every candidate has to be approved by the Mullah's. So the Mullah's are effectivly in control. Still, there are differences with the candidates. Would I vote under such conditions? No idea, I am struggle to find a party representing my views and I am in a western democracy.
The Democrats in the US have Superdelegates effectively vetoing candidates. So is the media and funding apparatus and the deep state by holding potential blackmail material. To be clear, I am not defending their system. I am suggesting democracy is not a panacea that automatically guarantees prosperity. Far from it.
In a democracy if you control all the votes of people you should be able to make changes in the government that the incumbent may not want. You can't do this in Iran.
