The country is bankrupt. It takes money to prepare a pilot for the airshow season. It takes money to deploy a jet plus ground crew to support an air display. The harrier guys have been busier than you would believe. All front line squadrons are taking hits on capability unless it is direct support of ground troops. You can't just take a jet for a spin around the skies at an airshow, there are stacks of safety issues to think about. You were lucky that there was any RAF presence there at all, (probably due to our historical links to the place). Wait until April to see how skint we are as a country and you will see why your statement seems a tad outlandish.
