I had to get a work visa for Brazil at one point. There was a fee breakdown, and all the fees added up to about $85, except a "reciprocity fee" which was an additional $55. I was curious, so I asked about it. It turns out that America charged Brazilians $140 for the visa application, so Brazil added that fee so that the total that Brazil charged American applicants was the same.
