In capitalist America, the class divide is so naked you can see it from the platform. The bourgeoisie ride in comfort. The proletariat are packed in. Even the trains are segregated, because the working class is oppressed.
Oh wait. This is China.
Then the workers always have a way to the ruling class, because the ruling class is loved by the working class. There is no class segregation. The people simply adore their leaders so much that they insist those leaders travel in sealed carriages, private sections, and quiet luxury — while everyone else stands. It is not privilege. It is affection. The masses would be heartbroken if the people who govern them had to share a seat.
