When you force other people to do your labor for free we call that slavery.
When an (invisible, abstract) system called the “church” forces it’s congregants to give it money (from their labor) for the “benefit of everyone”, we call that tithing.
When an (invisible, abstract) system called the “government” forces society members to give it money (from their labor) for the “benefit of everyone” we call that taxation.
I finally get it.
