Unless you're in the luxurious position of being isolated from real life thanks to trust funds or whatever, losing your job is kind of a big deal, and people shouldn't be casually wishing it on people.
Whether thats people who choose a career in a moribund medium 2 years ago, people who say dumb shit on twitter, or people who write "you ugly" on a note and think the person they give it to will find it funny.
