It depends on how much of your surplus labor your employer is stealing. It varies by many factors, not the least of which what kind of work you do, and very importantly, where you are in the world in relation to the imperial core, but in many cases, yes it is absolutely that much more, potentially even worse. But the graph isn’t meant to be read as an absolute metric, it can’t be since the size of each circle will vary so much depending on an individual’s circumstances. Rather the image is meant as a generalization to express some economic facts, basic Marxist principles that too few people understand.
