Why? Because they are a population that seems fully content with subjugation (even Marx noticed this).

So it's easy to see why they were such an ideal population for the intensive global expansion era of colonial empires. And it's even easier to see why they are perfect subjects for late capitalism now.

They are the culturally, psychologically, and physically ideal organism for the dominant system.

There's 1.4 billion of them. They are deeply eply socially stratified and so expect and even enjoy inequality. Their cuisine is cheap, meat-free slop. They live amongst trash and filth with no qualms. They don't care about the environment. Their reaction to death and abuse is blank-eyed indifference. They are physically and spiritually malleable. They not only adopt and internalize the demands of the dominant system as personal ambition, they believe this servitude makes them better than everyone else who hasn't.

Absolutely IDEAL subjects.

You, on the other hand, are not the ideal subject.
