What about all the human hosts that were taken off world? wouldn't it be terrible to be taken from your planet, enslaved, living in a society which was hugely advanced where you are enslaved, eventually the yeerk empire would have receded and you (or your great grandchildren born in slavery) would be stuck on the other side of the universe on another planet, without the resources to return to the more primitive Earth. A future of beind less educated than your alien neighbours and hosts restricts you to low level (the equivalent of manual labor) jobs and minority status, although on some planets closer to Earth humans might outbreed the even more primitive local population (for instance the hork-bajir homeworld or any other planet conquered by the yeerks where the people where more backward than humans) and this would be like a smaller version of Earth with Earth's massive problems scaled down to size. Ironically humans living as a minorities on these distant alien planets may end up better off in the longterm than those left on the war torn Earth... Earth itself would be that poverty struck little planet that brave cultural tourists (as described in Graburn's article) would visit, even so those cultural tourists would only visit safer parts of Earth such as America, Australia, Europe perhaps even Japan, but they would perceive this trip to be a great adventure and their parents would call them daily to make sure they havent been mugged and murdered because America's/Earth's crime rate is the highest in the universe, likewise many aliens would begin to assume that all humans are Americans/Westerners. it certainly wouldn't be a planet that you bother to consult in an intergalactic issue or whose alliance you would seek in an conflict-humans being so tribalistic and riven with internal strife and such high infant mortality, and humans breed so much and yet they can't feed their children... Earth would be called "the Lost Planet" in the intergalactic equivalents of Time magazine and the Economist.
There is a fanfiction there.
