Absolutely spot on, but unlike the banks who were allowed to "self regulate" and subsequently made a mess of things that nearly brought down the entire financial system in 2008, the aviation industry will be slightly different in some fundamental ways;
First of all, a single aircraft crash can not bring down other aircraft in a similar way the financial system is interconnected.
Second, there's always the knee jerk reaction to blame the pilots.
Third, there's the friendly media who barely do any real investigative journalism these days. It would take a monumental amount of effort to uncover any design faults.
Fourth, a single crash will not lead to a systemic collapse in confidence, but the production process is very interconnected. There is a lot of potential there for many countries, on a government level, to keep things swept under the carpet in order to keep jobs and prestige.
Just look at this aerotoxic syndrome as an example. Despite many tests and many cases, it seems to be impossible to get any action done on a regulatory and government level. There is simply too much at stake...
