INTRODUCTION

English translation pending.

CORE DEFINITION

Formulated by the novelist Terry Pratchett through the character Sam Vimes, the theory observes that a poor man buys a cheap pair of boots that lasts a season and must be replaced, while a rich man buys one expensive pair that lasts years, so the poor man pays more over time for worse footwear. The core proposition is that poverty imposes its own costs, because limited capital forces choices that are cheaper today and dearer overall, and those costs compound so that the gap widens on its own. The key qualification is that the mechanism is a lack of liquidity rather than a lack of judgment, so the remedy involves access to capital rather than advice to spend more wisely.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Total-cost view: compare the cost of ownership over time rather than the sticker price. - Liquidity diagnosis: ask whether the choice is forced by lack of cash rather than by preference. - Compounding check: identify where repeated replacement costs crowd out the ability to save.

Anchor fast decisions

Cheap goods fail sooner, so they must be repurchased more often, and the total spent exceeds the price of the durable alternative. The person who cannot afford the durable item also cannot wait to accumulate the money, because the cheap item must be replaced immediately. Each cycle therefore consumes the surplus that would have funded the better purchase, which is what makes the trap self-reinforcing.
