I'm sure there's nothing to see here or be worried about.
In the year's scariest economics book, Thomas Piketty argues that capitalism, left unchecked, subverts democracy by always and everywhere concentrating wealth at the tippy-top. That creates a class with so much economic power that they begin wielding tremendous political power, too. And then they use that political power to further increase their wealth, and then they use that wealth to further increase their political power, and so on.
You might call this the Doom Loop of Oligarchy: wealth buys power, which buys more wealth. You can see it playing out over the last two weeks in American politics.
