Those unfortunate house elves
In the wizarding world, there is a lot of evil. That is also true in the Muggle world, although it appears to be far more severe for wizards. Even apart from supervillains like Voldemort, some aspects of wizarding life are a little twisted up. Take, for example, the home elves. They are essentially a slave race with human intelligence.
How is it that this has only recently gained widespread acceptance? This is causing us some major troubles. If we could, we’d give a sock to every house elf on the planet.
