What is the biggest lesson that employment has taught you?

My biggest lesson was that decades of work means nothing if you become disabled (in the US).

You can end up with literally nothing and lose literally everything if you become disabled. Even if you still have skills, even though you worked hard to contribute to society for decades, it can all go away overnight and you can suddenly not afford food anymore. There’s no safety net, and you won’t learn that until you need it.

Because fuck you.
