The $237 Billion Nobody Invoices

The headline number is $818 billion. The number that matters is $237 billion — the value of care that 5.2 million family members hand over for free, mostly in their prime earning years, mostly without anyone calling it work. USC's model is unusual in that it bothers to count it at all. Most cost-of-dementia figures stop at hospital bills and nursing homes; this one walks into the living room and tallies the 6.8 billion hours a spouse or daughter spends managing meds, meals, appointments, and fear.

That accounting choice is the whole story. When the unpaid labor is invisible on the balance sheet, no one builds tools to make it survivable — they build for the line items that bill. A quarter-trillion dollars a year is leaning on families, and the market has mostly looked the other way. The first step toward fixing a load this size is admitting, in hard numbers, that someone is already carrying it.
