Hey, no ill will towards those who chose not to enter, or choose walk away.

I can only speak from my own experience. I perservered through many challenges early in my career and ended up where I did. Besides that, I have six or seven friends who I've mentored in the career. Everywhere from Mesa Capt, to Jet Blue, to AWE, to Delta, to UPS. None of them regret being in the career, in spite of them all being faced with significant challenges. Even my Aloha buddy got a new job within a month, family guy, never spoke ill of the career.

The job isn't for everyone. But to knock the career as being unworthy for all fails to take into consideration that all don't view things the same way. What's unworthy to you might not be a bad gig to the next guy.
