Swaziland
Swaziland, or eSwatini, is a country where about 80% of the 1.3 million people live on subsistence farming. The largely agrarian nature of the economy means that growth rates are slower.
But the country’s sole billionaire, Nathan Kirsh, is worth $5 billion. This means that if he even gave $2,000 to each and every Swazi, he would still be a billionaire.
