Care capacity is as real a form of ecological capacity as electrical capacity, educational capacity, or technical capacity — and as subject to deficit. It rests on a correction to a common assumption: that dependency is a failure state, the exception to a self-sufficient norm. It is not. Every human being moves through dependency — infancy, illness, injury, pregnancy, crisis, grief, old age, and every ordinary night’s sleep — so an ecology that treats dependency as failure has misunderstood human architecture itself.
The measure, and the deficits
The question care capacity poses is never how do we minimize the dependent but how much dependency can this ecology absorb while keeping viable both those receiving care and those giving it? By that measure, a society with extraordinary AI and exhausted caregivers has a capacity deficit; so does one where parents wreck their health to raise children, or where the old are abandoned because they no longer produce. This is systems coherence, not sentimentality — the care an ecology can carry is part of the capacity it has, and building it is one of the ways a field maintains its ecological continuity. It is not the same as healthcare capacity: healthcare asks whether treatment can be delivered; care capacity asks whether the field can carry sustained dependency over time, which makes it the broader and more fundamental of the two.
