Bernie Sanders, who is running for president in 2020 gave a speech a few days ago. He makes a claim which goes like the following:
Today the world's richest 26 billionaires, 26, now own as much wealth as the poorest 3.8 billion people on the planet, half of the world's population.

This is a surprising figure, at least to me (though maybe it shouldn't be.) I'm just wondering if it's true.
