Can you define what you mean by economic liberation? For most of economic history, I think the definition would have been freedom from famine and slavery and I think on both counts we've been wildly successful. Both basically only occur in failed states, where there's either no government at all (Somalia, Sudan, parts of Iraq and Syria) or the government is an authoritarian dictatorship (North Korea, Venezuela)

I ask, because I think you might be overestimating the ability of the current global system to produce "economic liberation", depending upon what you mean. A rough estimate of GDP per capita would put it at ~$20K if you adjust for purchasing power, less than $15K if you don't. That's well below what most people in the developed world would consider to be free of burden or worry and it assumes a completely equal distribution of all production, which is obviously unreasonable.

We need to continue to push the ball forward in growing wealth by continuing to improve productivity, which is going to require continued advancements in technology like mass adoption of AI.
