That’s an extremely reductionist perspective. The party doesn’t exist anywhere else and billionaires exist out there, so clearly there are more causes than merely the party. The party choosing to create conditions that allow for billionaires and not choosing to abolish them when they arise are definitely party choices, but when you understand it that way it opens up the questions "Why did the party choose conditions under which billionaires can emerge? and “If the party abolished billionaires as they emerged, what would be the effects and how would they interact with the conditions of national liberation, self-determination, anti-imperialsm, and the development of productive forces necessary to resolve contemporary contradictions?”
It’s still the fault of the party that billionaires exist in the first place.
