"airfare-level prices"? In Germany and Austria my experience was that flying was generally cheaper than the train, and sleeper trains more expensive still. I'm on a (day) train between Berlin and Vienna this very minute and it costed me €99 (one way!) where as a flight would have been about €50. You can get cheaper tickets if booking well in advance (months) but the same applies to budget airlines.
The joke is that airfare is way too cheap compared to the damage it causes - be it noise, exhaust gases or land usage for airport infrastructure. In addition jet fuel in Europe is tax-free which enables these ultra low prices.
This kind of Orwellian double speak is amazing. Lack of tax leaves too low prices for the consumer!
If you really feel that this tax is important, you can always tax yourself! Anyone you can persuade can join you, voluntarily. Just estimate the tax you owe (through this as of now not yet enacted tax) and send a cheque to the national treasury, with "Gift" as memo. They will take it!
I hope this voluntary taxation idea catches on.
