There is a lot more to spend it on. I'm gen-X, ADHD wasn't even heard of by most people until I was in college, and then it was only diagnosed/treated in the worst cases. Today most kids I know are on some medication for ADHD. A few years ago a friend of mine was told "too bad you are not 25 - I know what treatment you need but we can't give it to someone over 25" - he went to the Mayo clinic for his condition at 23 but the treatment didn't even exist yet so it was a waste of time.

In 1860 someone who went to a doctor would have worse outcomes than someone who stayed home. As medicine gets better over time there is more and more value in seeing a doctor. In turn more an more people are talking to their doctor about things that they would have just ignored a few generations ago. Sometimes this results in unnecessary treatment, but it also results in catching and fixing a lot of real problems that would have made life worse before we could treat it.

Part of the Obamacare mandate was forcing young men into health insurance policies when in the past they had a much higher opt out percentage.
