The institution where physical ownership of another human being was acknowledged as acceptable by society and ones "property rights" were enforced by the state is gone.
For example, debt slavery will never be eliminated, because it is a natural aspect of a limited lifespan, and else where I had explained to you (and others in some public posts) that without a limited lifespan entropy could not increase and the universe would be static with no future (past and future collapsed as in Godel's universe).
You cannot successfully top-down ban usury. The only was to eliminate it is to get people to voluntarily refuse to participate both as borrower or lender despite the fact that doing so is potentially profitable.
It will never happen,
unless you want a static universe. They tried banning usury in the Middle (Dark) Ages, and economic growth became static or declined.
I do not feel like explaining (Edit: I ended up
explaining more). Assemble the puzzle based on my past writings (but I've seen that you haven't quite assimilated all my writings).
It depends on your definition of slavery. My definition is broad and that is humans will never be equal, so some will always be subservient to others. Society can mask this as social obligations, slave level wages, or whatever, that is still slavery in my definition. I am a tax slave to Uncle Sam. People who think they are free even when they are not, are a form of satiated slave (Stockholm Syndrome being another example of that phenomenon).
