The airline industry is a prime example of how, sometimes, our quest for efficiency can be our downfall.
40 years ago, flying was much more comfortable that in is now. It used to be something people got dressed up for, took seriously, and got excited about. Then the race to the bottom began and airlines started cutting costs, lengthening flight routes and shortening leg room.
It works because we still pay for those flights. The demand is there. There is nothing stopping them from being more and more ‘efficient’ - aka - uncomfortable. Except, maybe, us.
