Life expectancy is a pretty good measure. The most important life expectancy raiser is not healthcare but access to food and clean water. Most deaths 100 years ago were caused by diseases which well fed people shrugs off. I'd argue that anyone who lacks food and clean water is poorer than even those who lives on the street in modern western nations.
