I agree, that topic is too often ignored. But the point of the book is not transitions from one economic system to the other, but transitions of centers of capitalist power from one region to another. Including centers of trade and centers of finance, that existed before capitalism really became the dominant economic system worldwide. Though capitalist production of commodities already existed in places. And then the book focuses on the hegemonies. France lost the seven year war and that was part of the reason why the revolution happened there. And even if it rivaled Britain for some time, the French empire never became hegemonic at the same global scale.
