> Order usually gets you better productivity and Autocracy usually gets you better military power. This design actually matches reality very well
It doesn't match reality at all in fact. The exact opposite is true for nearly all cases (China being the sole exception).
The major liberal economies are radically more productive than countries like China, much less the other 'order' type nations. The order economies, save partially for China (which is still extremely poor in the bottom 2/3), are on average impoverished, backwards, and with very low productivity. Even China is still shockingly backwards at a lot of common economic tasks, such as farming (they have ~1/40th the farming productivity of South Korea).
The liberal economies have dozens of major success stories, from Germany to Canada to the US to Sweden. The 'order' group has one, and only insofar as China liberalized its economy and moved away from a rigid command & control economy.
Autocratic doesn't get you a superior military. It typically gets you an economy that is bled and debased to feed the military, which ultimately is self-destroying. See: Russia, whose people are very poor ($8k GDP per capita; $4,000 median net worth). Meanwhile Putin diverts vast resources they can't afford at all, into military spending.
Liberal economies produce superior militaries pound for pound, because they can afford to sustain them over time.
