Since you specifically wanted me to answer about this topic: Preventative care has some nuance. Increased preventative services are not necessarily better, there is an actual ongoing debate about annual physicals in the medical community (http://time.com/5095920/annual-physical-exam/)

From an economic perspective, its not clear pushing for preventative will lower cost or increase quality. (many times it even has negative value, as reassuring a patient of being healthy when they aren't).

Fundamentally, if preventative cares are good people will naturally choose to invest in their own health. There is research showing that people are pretty good about healthcare utilization if they bear the cost (except poor peoeple)
