In this case it's very clear where wealth comes from: Bezos and the rest of the Amazon shareholders are severely underpaying these workers in violation of China's labor laws. Did you read the article?

> We can’t have stolen this wealth as not the smallest fraction of it existed in all the world before the industrial revolution.

The capacity for self-deception is always a bit surprising. Confronted with a clear and concrete case of labor exploitation and wage theft you insist, never the less, it is not labor exploitation and wage theft. That is economic insanity.

> How is removing demand for their labor going to make them wealthier?

There's no need to appeal to vague self-serving questions. The impact of labor standards on global trade have been studied and their impact can be quantified. Here, in particular, the California Effect [1] has been proven to be very effective in increasing labor and environmental [3] standards around the world. California alone could likely help here a lot by demanding regulatory advertising on these products. The first step would be to educate American consumers so they understand the enormous suffering that goes into these products.
