They're just saying that some skills typically come about with experience, and I don't think they're attacking you or unemployed people.

You talk about information being limited to job applicants, but interviewing is a two way street. Interviewers are human and also trying to sift through the information you deliver, and they tend to lean towards false negatives in order to avoid false positives.

Sometimes there is a gap and it really does come down to luck (or your experience in communicating during an interview).

My concern is more that the information which would develop productive experiences is missing. Yes, learning comes from experience. But you can learn the wrong things when your experiences are bad. Applying for work often does more to reinforce learning the wrong things than it does reinforcing successful things.

It's a lot like having many failed relationships. It doesn't necessarily teach you to try harder, it often teaches you to become cynical and careless.

No, of course not. Just as with the dating metaphor, there are a lot of people who will never be mature enough to accept that. But that's something they have to deal with themselves. I'm not their therapist. I can't "be productive" and help them fix their self-esteem issues.
