Because, for a start, without tax there would be no aircraft to fly.
Or airports to fly to.
Or safety systems to ensure people will take the risk of flying.
Or people with enough income to afford to fly.
Or, come to that, international stability that has been the bedrock of the expansion of international travel.
But all of that is ignored by these airlines who think that is anyone else’s business but there’s.
Except it’s not. Our duty is to make it our business.
And we could.
We could require that pilots and crew are employed by airlines, for example, or refuse them the right to land.
We could insist too that aircraft were owned in locations where there was accountability for that ownership – because that is key to the good governance that should be at the heart of safe travel.
And we could require that airlines be taxed on a unitary basis – i.e. from where they take off and land.
And that would just start the process.
