There are dozens of ways living in a cage can improve human life.
You won't be exposed to dangerous ideas and you might get a calorie allowance. There's little danger of an unwanted pregnancy, and you might be given labor-related chores or exercises to occupy your time.
The danger with all of these systems is what happens when they are abused. That's not a matter of if, just a matter of when.
We are building a cage around society. It's so slow you don't realize the shackles being placed around your ankle and your neck. But one day, when it's too late to protest, the switch will be flipped.
We're already living in 1984. We are always just a few election cycles away from 1934.
