Then those are problems to solve with social policy. Solving poverty by walking technology backwards isn't a solution. Technology is too powerful. Whichever society would be the first to renounce technology would also be the last because everyone else would say "Oh, that's why we like washing machines and self-driving cars".

And let's just say we lived in a unified society somehow. The net suffering of all peoples could only be alleviated by progressing technology forward and proper social policy. Removing one doesn't help solve the problem.
