- J. Pierpont Morgan
- Measured success in stabilized industries, completed mergers, and panics averted — outcomes, not philosophy, though his art collecting hints at a wider appetite.
- Milton Friedman
- Tied prosperity tightly to individual liberty and measurable results, wary of grand moral framing that could excuse bad policy.
- Charlie Munger
- Cared about wealth mainly as evidence of and vehicle for good judgment and a well-lived, rational life, not as an end sufficient in itself.
- John Maynard Keynes
- Treated economics as a tool for enabling a fuller civilized life, and warned in his Versailles writing that purely punitive economic terms would wreck more than balance sheets.
- Adam Smith
- Wrote two books, one on sympathy and one on markets, insisting they were about the same question — prosperity mattered because of what it let people become for each other.
