The numbers say that people in China are now better off than people in Europe. And this is with China having to rebuild itself after a civil war and the destruction in WW2. Meanwhile, the reason the west is rich is because the west colonized the rest of humanity and has been brutally exploiting it. Claiming that the west is rich because of liberalism is factually wrong. The west is rich because it enslaved billions of people across the globe plundering their labour and resources.

What specifically is the bad information you’re referring to. I’ve provided you with the actual numbers here.
