Building wealth comes down to habits you control, not the income you earn — encouraging news for ordinary families squeezed by rising costs.

• Housing, health care, child care, and inflation costs are out of your hands, but your savings rate and investing habits are not.
• A family earning $50,000 that invests steadily from age 25 to 65 can end up wealthier than one earning $150,000 that never invests.
• Wealth comes from time and compounding, not from a big paycheck.
• Standard poverty measures miss this entirely — they can't capture what decades of consistent investing does for a family.

Outlook: Costs will keep climbing, so the families who stay in the market and keep buying assets will pull ahead of higher earners who don't.
