Part 2: The Hard Lessons from Practice

Lesson 1: Theory says "invest in capital," practice says "invest in social capital."

Money sticks where it lands, not where need is greatest. Theory assumes perfect allocation; practice shows local elites capture funds. Solution: Transparent participatory budgeting (Porto Alegre, Brazil).

Lesson 3: Behavioral constraints dominate structural ones.
