Why? Because almost any fool can drive a car and easily judge what is and is not incompetent driving. Very few people can fly aircraft, let alone airliners, yet they deem themselves capable of judging "competence". Farcical.
That's an amazing level of arrogance you display there. I doubt it would have any real value in a court of law. Similar attitude that doctors used to have - you can't sue me! I'm a doctor! I'm above the law!
So the salaries for professional aircrew are plummeting, the T&C falling and very few people are choosing to pursue aviation as a career.
Any profession goes through ups and downs, it's called supply and demand! Right now the industry is in a rut but it won't always be like that. Hardly an argument though that justifies incompetence.
Add to this the potential for professional crews to be judged by clueless laymen as incompetent and you have the makings of the whole industry grinding to a halt for lack of anybody willing to subject themselves to such stupidity. Lets just add some money-grubbing lawyers into the equation to really accelerate this stupidity eh!
The whole industry grinds to a halt? Sounds like an emotionally exaggerated outburst to me that I can hardly take serious.
