Principles of Maximum Social Advantage

1. Equivalence of Benefit and Sacrifice

   • Public expenditure should continue until the benefit derived from the last unit of spending equals the sacrifice made to raise that unit.
   • Example: Building a flyover should provide benefits (smooth traffic) equal to the costs incurred (taxes collected).

2. Marginal Satisfaction

   • Resources must be distributed such that marginal satisfaction from different expenditures is equal.

3. Equitable Distribution of Taxes

   • Taxes should be distributed so that the marginal utility of the money paid is equal among all taxpayers.
