You probably know this, but for the GP:

It's not clear whether the 1500 hour rule directly improved safety. Both the Colgan captain and the FO had more than 1500 hours at the time of the accident. What the rule did unambiguously is severely restrict the supply of new pilots to regional airlines. This significantly improved quality of life for regional pilots, who prior to Colgan were effectively making minimum wage or worse. (That may have indirectly improved safety, by making pilots more well-rested and fed...)

Another point of comparison is Europe, which has a not-dissimilar safety record, but still allows FOs to have 250 hours. That said, from what I understand, they have a very different training culture where students start in a multi-crew environment very early.

I remember reading about the typical lifestyle of a new regional pilot. Low wages, long hours, and often flying many hours as a passenger to get to work (living in Pitts, grabbing the first flight to NYC to work, etc). It sounded miserable.
