The way Americans vote doesn’t correlate with what they want. When the rich want something, they engage with the established systems to work towards their goal. When the people want something, they tend to ignore the systems that are made specifically to hear their voices, and do everything but use them. Then the system works as intended, and everyone’s surprised.
We can’t really blame an average American, they’re overworked, uneducated, solitary, angry, dumb, and confused. But it is what it is.
