Great site. I think the biggest things the general public doesn't understand are:
1. you have to maintain excellent health throughout your career or you will lose everything you worked for (also, impeccable personal record)
2. how long and hard the road to a major captain seat job is
3. pilot hourly pay rates equating to regular job wages
4. loss of a pilot job forcing you to start at the bottom at a new carrier (if you can even get hired somewhere)

You hit on all of these topics. But unfortunately, I don't think the average non-pilot can ever really process this stuff no matter how many times they read it or have it explained to them. That's why the public has no sympathy when some airline management screws over the pilots again and again.
