I am not sure if this is the right space to post this: Jason Hickel and his colleagues have just launched this website collecting their work on global inequality, including many aspects, such as unequal exchange, climate injustice, carbon inequality, debt and structural adjustments programs. It’s very comprehensive and full of graphs that can be very useful for agitprop.
If anyone talks to you about USSR, Russian, or Chinese imperialism show them this graph:

Now that I think about it, it might be the key to being able to answer “does GDP alone make a country wealthy, or does GDPpc alone make a country wealthy, and how does a low-population-high-GDPpc country compare to a high-population-low-GDPpc country”.
I think I would have made it ln(pppGDP) * ln(pppGDPpc).
