What is your point of view concerning medical spending on the elderly

In recent years, the medical spending on the elderly in the US is increasing. Few people really know the reason or driving force behind that. While elderly nowadays in many countries receive social security and spend more in medical care, some people argue that :" because elderly peopel are generally not part of the labor force, they represent an economic drain on the local economy." Well, i am thinking that the older people must feel very disappointed if they contribute a lot to the society when they were young and get little care from the society when they get older. Suppose now we decrease the medical spending on the elderly people. Will people stop working hard concerning their poor medical condition when they get older? Or they may work harder to reserve enough money for the rest of time after retirement?
