For a more nuanced and detailed account of Soviet bureaucracy, and the construction and dismantling of Stalinism, see The Soviet Century. Combined with The Half Has Never Been Told, it is worth wondering whether industrialization is possible without slavery. Also, it is worth questioning Hudson’s characterization of China as pursuing “socialist” policy, rather than being state capitalist — he basically just assumes such points. Though this was intended as a speech to be delivered in China, so maybe he felt the need to pander on that point a bit.
