Premise: A society benefits when members of the society are educated.
Premise: The more educated a person, the greater benefit to society that person becomes.
Premise: Slavery is immoral.
If the premises are true, then the moral question is: who should pay for the education of one to enable that one to benefit society? The individual, or society?
Is it moral for a society to make the cost of an education that benefits the society so high that the individual must become indebted through loans that cannot be discharged in bankruptcy, loans that are amortized over 30 or 40 years? In such a society, does not the society reap the benefits of the individual’s education yet place the burden on the individual?
Analysis: A society that forces individuals to bear the burden of the cost of their education is based upon placing their educated members of the society in economic slavery.
Conclusion: If slavery is immoral, economic slavery is immoral.
Moral societies bear the burden of educating their members.
