It's interesting to ask: how many billionaires are there in the world? It turns out, approximately 3,148 people. It sounds like a lot, but considering the world's population, it's just a drop in the ocean.

The statistics are truly astonishing when you look at the top of the pyramid. Only 19 people have a net worth of over 100 billion, and 6 have surpassed the 200 billion mark. And in fact, one person has pulled away from everyone else — his wealth exceeds 800 billion. Elon Musk tops this list with a net worth of about 849 billion dollars.

And if you look at millionaires — there are about 60 million worldwide. That's a completely different story. It turns out we are living in an era of historic wealth concentration. The question is, are you actively building your wealth or just watching how it happens to others?
