There are 11 million people living there. It would cost 3 trillion dollars to give each about $300,000 or about the mean wealth of an american. It would probably cost less than 3 trillion to win such an election.
This assumes that people would agree to sell their votes. With that said, I am very much against dictators, benevolent or otherwise. But I would understand.
As support, I would point you to this 10 year old article on Moammar Gadhafi, where he was estimated to actually be worth roughly $200b USD - an unheard of number in 2011. https://www.forbes.com/sites/edwindurgy/2011/10/25/did-moamm...
This week, if Bezos were not divorced, he would be worth $300b USD: https://www.celebritynetworth.com/articles/billionaire-news/...
And finally, the ProPublica Peter Thiel $5b USD ROTH IRA is worth *double what Forbes thought Thiels entire net worth is per the 2020 Forbes Billionaire List* (he is on page 3... look at the massive jump in the animated graph!): https://www.forbes.com/billionaires/
That said, the IRS had 20 years of tax returns stolen from it which would detail the richest Americans, and so it is unlikely anyone in the USA is a trillionaire.
But yeah, so many countries are so tiny (economically), I’d be shocked (from my afterlife in heaven looking down with god) if most of them aren’t really indirectly controlled by some centi billionaires.
