The issue is that we are enabling people to travel long distances too cheaply.
What about short distances? Why is it cheaper to fly Berlin-Stuttgart than to take a train? it makes absoutely no sense.
Yes, let's make things more expensive, cause we experts know best. That poor guy that needs to attend a family funeral, he's a loser that should stay home. Inflation for the Win!
And above all too quickly. Per kilometer, flying is roughly as polluting as driving, but nobody would think to drive across a continent to go to the beach.
