ADVICE

Use Education But Don't Over-Rely

  • Teach financial literacy broadly but set realistic expectations because schooling reaches higher-income groups most effectively.
  • Use targeted education but also design systems that bridge knowledge gaps for lower-income people.
INSIGHT

Mistakes Subsidize The Wealthy

  • Consumer mistakes create cross-subsidies where savvy customers indirectly benefit from others' errors.
  • Campbell calls this a reverse Robin Hood transfer from the poor to the rich in mortgage and card markets.
ADVICE

Make Products Comparable To Let Competition Work

  • Simplify products so consumers can compare price and quality, which lets competition lower prices and raise quality.
  • If shopping is based on brand familiarity, competition will waste resources on advertising and empty branches.
