Spending Is Someone Else's Income

Mechanism

One person's spending becomes another person's income.

When spending rises, incomes elsewhere rise. When spending falls, incomes elsewhere fall. This creates propagation: local changes in spending can feed through the economy as income changes.

Source Support

Dalio states this repeatedly, first around 00:04:43-00:05:49, then again during the short-term cycle and deleveraging sections.

Why It Matters

This mechanism is the bridge from individual transactions to macro cycles. It explains why credit expansion can raise incomes and why spending cuts during deleveraging can worsen debt burdens by reducing income faster than debt falls.

Boundaries

This mechanism is directionally useful, but the source does not model leakage, savings rates, imports, taxes, sector balances, or timing differences.
