A cursory look at the fall of extreme poverty across the world, over the last few decades, is enough to refute the idea that the world is largely based on exploitation.

The last 100+ years have also been atypical. Two world wars which disrupted economies in ways that lead to redistribution, huge changes from the end of European empires, the fall of the Soviet Union and communism, and technological advances that automated work but created may new jobs.
I would be very reluctant to assume a continuing trend from that.
You would think that a great reduction in extreme poverty would give people pause, but it is almost always barely acknowledged. The strange conclusion is that people who tell you they care the most about poverty do not actually care about it in the slightest. It is just a vehicle for their resentment.
Maybe they've grown. Is Bangladesh at the stage where they outsource labour to other countries yet?
Again, what does that have to do with exploitation?
