We walk through Book Five of The Wealth of Nations to map a state that defends, adjudicates, and builds wisely, then pays for it without killing growth. From militias to standing armies, fee-based courts to salaried judges, turnpikes to basic schooling, and taxes to debt, we test what holds up now.

• defense as a professional, civilian-controlled standing army
• justice as predictable law and salaried judges
• public works funded by user fees where feasible
• education to offset division of labor’s civic costs
• incentives in universities and churches
• four tax maxims and ability to pay
• why land taxes beat mobile capital taxes
• state property and monopolies as bad revenue
• debt, consols, and fiscal illusion
• Smith with Hume and public choice echoes

We do have one more episode, which is a summing up and taking stock of why the Wealth of Nations still matters today. It will post Tuesday, February 24th, 2026.
