Slavery is indeed gone if we define slavery as the legal and socially acceptable practice of reducing one individual to the status of another individual's property.
SJW's semantic obfuscations aside, slave labor is socially acceptable and legal in Asia. The Chinese autocrats used it to undercut USA wages.
I'm calling bullshit on Marxist social justice moralizing.
Where slave labor is economically competitive, nature provides it. All this posturing about the power of man to be more noble, is social justice bullshit. The social justice warriors annoy me so much with their holier than thou lies.
Nature is competitive.
Being in touch with reality is the most rational. These moralists who go off into bullshit which is not reality are very dangerous.
