At this point in history virtually every human on this planet is enslaved whether they know it or not. This is not the crude and primitive slavery of ancient times, it does not rely on whips and shackles to keep the oppressed in their place. These tools have been rendered obsolete by much more sophisticated methods.
That most of the enslaved are unaware of their condition and would in fact argue fiercely that they are free is a testament to the effectiveness of these invisible chains.
You've heard the expression "Money makes the world go round". There's truth in that.
