> Not unusual at all. 1500 hours is the standard in most places AFAIK.
You're fixating on a number rather than the meaning behind the number.
The US ATP certificate is 1,500 hours, and has been for a long time, but now an ATP is required for US airliner operations. (There is also an R-ATP, starting at 1,000 hours.)
Before 2010 (ie. before Colgan), a commercial multi (about 250 hours) was sufficient for Second-in-command" (SIC) globally. Only the US requires ATP for all stations, and it's because of Congressional "we have to do something."
As a result, all US "regional airlines" (aka union-busting pricks) have either stopped operating, or are in the process of shutting down, since there's no qualified cheap airline pilots.
Having said that, there is a cutout if you attend a Part 141 school: "If you complete a degree in an aviation field from a qualified university, you can get a Restricted ATP certificate, or R-ATP, once you've accumulated as little as 1,000 hours of flight time and are at least 21 years old."
Sadly, the "aviation degree" is a poor choice for most students, as they need a degree in another field like accounting in case they fail their FAA medical, thus instantly ending their pilot career.

"Although it did nothing to address the specific causes of the crash – improper stall recovery technique and pilot fatigue"

The above pilot training scenario is bad, but the airline mechanics situation is far worse. Thanks to our lawyer-driven political system, we've hollowed out the leader in aviation into something resembling a failed African state.
