Is Inequality Inevitable? (Scientific American) makes a compelling argument about wealth that I’ve always suspected but lacked support.
The key ideas I took away from Bruce Boghosian’s article are:
- The affine wealth model reveals the tendency towards wealth concentration or extreme inequality even if the outcome of a transaction is chosen randomly.
- If the transaction outcome is random, then luck plays a bigger role in amassing wealth than most people think.
- Wealth tends to flow upward.
- As a result, the free market is essentially a casino you can never leave.
- Fortunately, redistribution sets a limit on inequality, but it’s not necessarily a tax (see chi, zeta and kappa parameters of the affine wealth model).
