This is what’s known as Hostile Architecture. Its purpose is to discourage homeless people from sleeping on benches and other items in public areas.
Rather than using the money for a productive solution to our homeless problem places are doing this all over cities instead.
You will find that in the end, you will pay. You will pay to be born (already happening), pay to live (already happening on an obsessive scale) and you will pay to die (already happening). But you will eventually pay to breathe and to be allowed to eat. If you make any extra money during the month you will ‘pay’ for that extra to be taken away because you can not have extra.
You will be controlled.
