The default setting is Greyhawk (as others have already pointed out), so I guess it depends on how 'generic' your view of Greyhawk to be... either way, I think it's fairly irrelevant.
Yes, there's a standard baseline in terms of treasure and power relative to character level. It may or may not match up with your vision of what an X level character can accumulate or accomplish. Big deal. If it doesn't suit your needs adjust it, but be mindful of the consequences, especially as it relates to appropriately challenging PC's. It says as much in the Core Books. Arguably it's an added step, but it certainly isn't that difficult. CR's are a guideline, but they aren't etched in stone, and I don't think anyone implied as much.
As for the speed of gaining levels, to each their own. Personally, I like the idea of being able to get close to level 20 after a year of gaming. Not everyone can (or wants to) devote a decade of their life to a single campaign, heaven forbid.
And just because you (and I mean you in the most
generic way possible) may have a character that has taken 4 years to reach level 15, and I have one that reached level 15 after a single year of gaming, it doesn't make your character any 'better' than mine. If you think it does, here's a bit of advice. Find a pair of ice tongs and a helpful friend that can keep a secret since you likely have some large foreign object stuck up your backside.
I never thought I'd say this, but I actually miss people bitching about the Harm spell, Half-Orcs, and Rangers...
