Too many comments are trying to overanalyze, or just show off their insightful cynicism.
We do airshows because they are cool. Lots of us love airplanes. Humans do all kinds of activities for entertainment that are not strictly justifiable returns on investment. I hope we never get that boring, though every year we do seem to go that direction.
It's worth questioning what the costs are, though. I love military aviation more than the average Joe, and seeing these jets pushed to their limits is pretty gratifying. But this isn't a football/soccer pasttime, the E/A-18 is an expensive F/A-18 block and the aviators are an asset of national security that take decades of experience and millions of taxpayer dollars to train. The losses sustained by the Blue Angels alone is stomach-churning, and they're widely known as one of the most professional groups around: https://en.wikipedia.org/wiki/Blue_Angels#Team_accidents_and...
The net benefit is marketing, and little else. As much as I enjoy watching airshow jet maneuvers, I have to acknowledge that the USSR only sent their Sukhoi pilots on-tour as a publicity stunt to increase their exports. Same goes for the US, France and China.
I grew up in a time a whole lot more was spent on air shows.
They do it because it’s awesome and it is one of the few opportunities they get to show off their gear to the public!
I would say it's part of the US culture. It's not a thing in Europe (one reason might be practical reasons. We have less space to do it safely).
No. They are for recruitment and showing other nations what is on hand in case they want to mess with them.

So in response you select the most naive take?
