In my last post, I forgot to mention that in 2004 they asked whether American trade policy towards other countries was fair or unfair. People consistently rated American policy towards them as more fair than their policy towards us, but there were some differences in the judgments regarding different countries:
The more fair people saw a country's policy towards the US, the more fair they saw our policy towards it. As I mentioned in my previous post, most people have no experience they can draw on to make these judgments, so I think it's just general feeling about whether we are in a cooperative or antagonistic relationship with them.
The survey also asked about American trade policy towards "poor countries": 51% said it was fair, 36% unfair. That is considerably less fair than perceived policy towards the other countries: it is equal to the lowest value on the y-axis. They didn't ask about poor countries' policies to the United States. If you extrapolated from the numbers here, you would say their policies must be seen as highly unfair to the United States. But I don't think they would follow that pattern: rather, to some extent people figure that rich and powerful countries will mistreat poor countries. There's some evidence of that in the figure: of the countries included, Mexico would be seen as the weakest economically (China's per-capita GDP was smaller, but it was already seen as an economic power because of the combination of a large population and rapid growth). And Mexico is below the line, meaning that American trade policy towards it was seen as less fair than would be expected given their perceived policy towards us.
