This writing prompt from about a year ago on the other site is relevant:
Aliens take over the Earth. They then announce that they will be forcing the humans to work a “tyrannical” 4 hours a day 4 days a week in exchange for basic rights like housing. Needless to say they are very confused when the humans celebrate their new alien overlords.
Link, if you wish
I did a similar one a few months back too.
A civilization capable of interstellar imperialism* would be focused on long-term exploitation of less primitive societies, so they would probably manage us better than the current elites do. A more educated, healthy worker is simply more productive than the alternative, especially in the long term.
- unless it is some kind of swarm of space locusts that just devour everything in their path.
Boy, somebody hasn’t learned about colonisation history!
Targeting primitives is about right, though!
I would find it more likely that they wipe us out to make way for colonizers of their own. They probably have no use for us, save maybe a couple to keep on display in a captive breeding program. They would likely have the technology to perform any work we could, but better and faster.
