The only practical way I see to assign a value to a life is the NPV of future economic value.

Unfortunately, this means most 90-year-olds get a negative number.

But even on other, non-practical measures of the value of a life, I agree with you...I see no way to argue that the 5-year-old isn't more valuable. Give the 5yrold an expensive and prolonged terminal illness, and the calculus might change.

What about the fact that the 90 year may still be able to self support while the 5 year COSTS money. The 5 years old value is untested future potential economic value. But any 5 year (other then infant models) have -economic value, no?
