daria,
There are a lot of misinformed people out there, unfortunately they are usually the ones who have it all on a plate. If they had to make an effort they wouldn't bother. They may well be bored of the job within a few years (if they get a job!), but I suspect that doesn't matter to them much aslong as they can pull birds with their uniform. Don't let it get to you, just get on with what you're doing and be happy. I'd still say the majority of people are motivated by a love of flying and aviation and that's what gets them by. Most people are happy to fly whatever, some only want to fly jets but you have to appreciate that this isn't always due to an 'I only want to fly for airlines' attitude, but often because they would be unable to service their loan on any pay other than airline pay.
