Upgraded and repackaged slavery
Slavery never came to an end, it was simply modified in such a way that the masses could be duped into not even seeing it as slavery at all but instead seeing it as "necessary for the good of society". This is the indoctrination of the religion known as 'Statism' AKA - the belief in government and authority. If you honestly believe that you are free and that slavery came to an end, you are under the statist form of mind control put out there by the ruling class and they have you exactly where they want you.
For them, the best, effective and ideal slave is one that not only believes that they are free but will deny outright the claim that they are enslaved. Even worst they will defend their own enslavement, and make excuses for it and even vilify anyone who tries to speak out or fight against it.
It is impossible to enslave a soul, very obvious if you limit the physical body, but imprison the mind and you have a slave that doesn't even realize they are a slave.
It's really quite ingenious. What is the solution? Educate yourself and reprogram your conscious and sub/unconscious minds to the point where you are able to see through the manipulation and mind control. Learn about, and align with, Natural Law, Truth & Freedom!
