Episode notes
Standing Armies In Commercial Societies
- Smith argues commercial societies require professional standing armies rather than militias.
- Properly subordinated standing armies preserve liberty better than ineffective militias in advanced societies.

- Smith insists on salaried, independent judges to avoid corruption and arbitrary fees for justice.
