If we look back through our lives there will almost certainly have been long periods when the only reason to see a doctor might have been for a repeat Pill prescription or for a poorly child.

Of course with an increasing elderly population, because we are surviving the illnesses which bumped off our grandparents, there is greater need, so why does a government with all the bean counters at its disposal not work that out in advance?

It's called forward planning, but piss-ups and breweries spring more readily to mind.
