Healthcare will likely go through a bust period once enough of the aging population dies off. The industry itself will always be needed because health problems affect everyone, but the highest healthcare bills people have in their lifetime are when they reach old age. By old age, more prescriptions are used, hospital visits become more frequent, and installations of in-home mobility aids are more common. Then you have the choice of live-in nurses or hospice depending on severity of problems, and money available. Once enough of a threshold of the elderly die off, there will be cuts to healthcare related jobs, as there will be fewer people needing those services. This entire process will probably take another twenty years to come to fruition, but the healthcare industry takes for granted the amount of dying elderly they have, as the only generation to be near the size of the boomers are the millennials.
