20-Year Prospect
The act of giving a massage has likely been with humankind since before we learned to use anything besides our hands as tools. Unless some mad scientist develops some way to transport every hand on Earth to the moon, we're pretty sure massage as a thing people can get paid for will exist.
The best news of this entire profile has been saved for last: the job outlook over the coming decades is awesome and getting awesomer. Job openings for massage therapists are expected to increase by a whopping twenty-two percent over the coming decade (source).
We realize this is massage and those numbers might not mean anything to you, but twenty-two percent of 168,000 jobs means there'll be 37,000 new jobs by 2024. We think that's a pretty great sign for those trying to break in to this field.
