OK then:
The 12 fold increase in armament production is not completely artificially driven by the Chinese state, it's market driven.
The USSR did not produce what Stalin wanted from 1930 to 1941 (ridiculous amounts of tanks, artillery, obsolete planes, etc,), but what the USSR deperately needed (grain, dairy, meat, vegetable fats, modern planes, trucks to supply the tanks, etc,).
Mussolini and Hitler did not waste a fortune building useless battleships and Hitler did not ignore Schacht when he suggested increasing massively vegetable fat production and petroleum reserves, since vegetable fat is the most efficient and concentrated form of energy for humans and can be burnt in Diesel engines, choosing instead to produce ridiculously expensive synthetic fuel.
Whenever a dictator's whim determines demand, there is no capitalism. Capital does not flow toward demand, but toward that whim, preventing supply and demand from interacting freely and driving a healthy economy, the principle of capitalism.
Your idea that an aristocrat exploiting his fiefdom by the sword is capitalism is quite outdated.
