Looked at in simple terms, if the prices are too high and the airlines shrink too much due to lack of passengers (all possible) then too many interested parties with too much (multi-billions) invested will lose out. Someway and somehow, perhaps with you and I paying for it through taxes, the massive investments will be protected for the most part. Money will be printed out of thin air and things will continue.
If not, then it's aluminium for everyone, holidays in Bognor Regis and private jets for those with their wealth still intact. ;-)
