I suppose they meant capitalism runs away to Corporatocracy.
But this is misleading as corpratism isnt really a system of government but rather represents a distribution of power. where communism is a different system than socialism... like one can argue communism is the "pure" form of socialism more easily than one can argue corpratism is the pure form of capitalism.. but we are in the weeds here.
Personally I would say all of these are cvery different things (communism is where both the means of distribution and productions are owned by government, and socialism is where just the means of production is), and almost no countries today are either of these most countries are some form of capitalism with social welfare programs, and I would argue social welfare is not a reduced form of socialism.
