I think you're reading into it too much. "250 hour wonders" is more calling them the anomally that they were in being able to be hired at that low time. No more, no less. Some low timers were great to fly with... some hadn't been given enough chances to find themselves or be weeded out yet.

It was what it was and hopefully will never happen again. No one should be allowed to sit in an airliner cockpit without a decent amount of command experience.

I chose to stick it out and build my time instructing, flying small time corporate, and doing aircraft sales knowing the command time would do me well compared to the others that took the short cuts. All the while learning everything I could about airliners, operating them, and the culture. I didn't stay any longer doing that than I had to until I could get hired, though (it was a more difficult time to get picked up by the regionals).
