I was debating bringing up disruptors when I made the grandparent comment. My 2 cents: they can shift the balance of power at the very small scale (e.g. "some random nobody" getting rich, or some rich person going bankrupt), but the large scale power structures almost always remain largely intact. For instance, that "random nobody" may well get rich through the sale of shares in their company - now the company is owned by the owner class, who were previously at the top of the power hierarchy.

Random nobody whose parents just accidentally happened to be a millionaires and/or live, work, and study in the top capitals of the world.
