A woman who has been a man previously,could probably rule the world
If such a thing could happen in real life,i think it would be a great chance for that person,if that person is poor.
Why so? Well,i think women born as women,often they dont fully realize the power they have,for lack of self-confidence,and the ones who realize it,well,they have an Onlyfans and are billionares in Dubai. But,as you was once a man,you perfectly know that a woman can obtain everything she wants,just playing flirty from time to time. Also,women sometimes take decisions out of love (like men do too) so they dont take the "rational choice" (aka money),while,being a man that just happen to have the "instrument" of a female body,you could take the "rational choice" without feelings being involved. So you could use that power at 100% and,starting from the bottom,with the right choices in who to seduce,in a few years you could become one of the most powerful people in the world. Dont believe this? Well look at many "online celebrities" who are milionares or some models,actresses,and probably politicians too,without big talent at all..they are your proof right there. It requires brain,of course,so thats a merit.
About transgender people: that would work too if they look exactly like a woman,and keep their previous life hidden,to avoid prejudice in their rise for power.
