Warren Buffet is the definition of oligarchy. Dude runs a rail and insurance monopoly while buying large top stocks for yield. He maintains a persona of this traditional and nice family dude who is old and wise. But this is the US, and people are ranked/valued by how rich they are regardless of how it is acquired.
Still, he avoided political scrutiny (say comparing to Musk or Bezos) by maintaining this image. That was wise.
