In terms of overt slavery, most groups have been both slave owners and slaves at different times. You're right about slaver never ending, it was just made covert, though even overt slavery still exists too.
I realized that most of what people call 'society' was in fact a very cleverly-crafted, and insidious slave system. That's why over the course of years I removed myself from it. Now, I live almost entirely outside the system, for which I'm deeply grateful.
I will say, however, that these times are very potent and special, and the whole slave matrix is in the process of being destroyed, and is about to come crashing down. 😁 🙏 💚 ✨ 🤙
