Zim,
I notice that slavery has been, as it has to be, REDEFINED in order to make your assertion. That is a cunning trap.
So things like child marriage makes up most of the world's population of slaves under this redefinition. But "child" has a slippery (non stated) definition. Is it 21, or 18, or 16, or puberty, or is it based on intellectual and emotional development? So arranged marriages, and underage marriages, must all be “slavery”, regardless of whether they are culturally or biologically supported? Regardless of whether they end up as lifetime, reasonably fulfilling relationships and propagate the families?
Let's face it, few if any ever stop maturing. And I'd argue at least half the population NEVER takes responsibility for themselves and stops looking for "entitlements". so more than half the population ever escapes childhood. So more than half the population is rooked into marriage one way or another. So more than half the population is ENSLAVED according to your source definition?
I know a lot of men and women who are trapped in marriages they can't escape, even though they are profoundly unhappy and feel compelled to continue? And legally sanctioned. Very akin to prostitutes with pimps, in many cases. Certainly not free; absolutely not free to leave. So..."slavery"?
And military personnel, they can't leave without being sanctioned, jailed, or worse? Do you think the citizens in Ukraine can all leave? You can bet your bippy, the vast majority want to. Wasn't the draft a form of slavery?
But THAT IS INTELLECTUALLY DISHONEST and leads to Stinking Thinking, subjugation to authority, and atrocities like the Forever War when you allow words to be redefined to meet your desired outcome half way.
*I* would say that "taxation without representation" is just as much a form of slavery as childhood marriage. I am represented by this government not at all. So *I* am a "slave", by your own weak logic.
And, therefore, since next to nobody on the planet is represented by the authorities which tax them, ALL EIGHT BILLION PLUS OF US ARE SLAVES.
Now, in truth, I actually do think nearly all humans on this planet are slaves. Certainly I think you are. But if you are going to present arguments based on words, and allow the words to be ill-defined, you have a bigger problem than slavery.
