A better world is possible. Capitalism in the modern age is dying imperialism. Western supremacy is built on the backs of the global south, not any intrinsic superiority of capitalism to produce good results but for its systemic drive for plunder. Socialism, where humanity takes the reigns of how we produce and distribute away from the profit motive, is the way forward. If you want a place to start with theory, I made an introductory Marxist-Leninist reading list, feel free to give it a look!
