## Statement

The distribution of net household wealth is markedly more concentrated than the distribution of income: across major economies the top 10% holds a majority of household wealth while the bottom 50% holds close to none. This stock-level disparity is distinct from, and larger than, the income-flow gap recorded in IS1 — a household can earn a modest income yet hold no net wealth at all, and the lower half of the wealth distribution is compressed against zero in a way the income distribution is not.

## Causal links

- causes ← [IM1: Capital returns systematically exceed labor-income growth](https://aboard.untype.me/claims/IM1/index.md) (strength 0.60) — The r > g mechanism compounds returns on existing capital stocks faster than labor income grows, so net wealth — a stock — concentrates faster and further than income does. That is precisely the stock-vs-flow disparity IS3 records, and it is the same channel by which IM1 already drives the income-share symptom IS1; here it acts on the wealth distribution directly.
