The core idea of capitalism is that you spend money to make more money. Rich get richer is the basic idea, you invest and those investments make you more. It very necessarily leads to oligarchy when left unchecked.
The core ideas of capitalism are private property and free market, not "rich getting richer".

Great, let's not leave it unchecked. Unlike other -isms, capitalism does not need to be treated like an ideology to work. Also, maybe let's not attribute obvious failures of the political system to the underlying economic system.
