There are no trillionaires. I mean in reality I am pretty sure you could get every vote you wanted for $5,000 each. Average annual income in Haiti is $500. So 10 years of salary. Also only about 6 million voters in Haiti and you only need half of them so you could be president for $15 billion. Likely most people would sell their vote for their annual income, that means a total of $1.5 billion. I would not blame them either, extreme poverty is a terrible thing and for many the adage 'any port in a a storm' is likely true.

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.
