You seriously need to do some home work on lens prices before you make such comments.
Since we are discussing in a APS-C DSLR thread lets discuss the best lenses made for APS-C DSLRs:
Canon EF-S 17-55 f/2.8 L IS = $1019
Nikon 17-55 f/2.8 ED-IF-AF-S DX (without Image Stabilization/VR) = $1399
What? more than $380 for a lens that does not even have image stabilization? but no problem, let us continue to sing glorious songs about Nikon/Sony sensors bcoz there is magical DR and 6 additonal MP in them, so they are going to elevate our images to the magical proportions of a unicorn's behind from Narnia 
Then lets go on to the popular zoom range lenses for wild life photography:
Canon EF 100-400 L IS = $1459
Nikon 80-400 ED VR = $2697 (even the old, which most Nikon users used to bad mouth, was selling for $1698)
Over $1200 difference for the newer version of the Nikon 80-400 lens ... but hey we like to live in the world of ignorance, therefore, we will only crib about how Canon lenses are "not comparable to competing products in the same price range" bcoz the new 24-70 f/2.8 L II is $300 more than the older Nikon lens 
Look. the simple truth is: no matter which system you choose (Canon or Nikon) you will end up spending pretty much the same amount of money on equivalent gear ... I've used (and continue to use) both Canon & Nikon gear, so I am speaking from my personal experience.
Sigma 17-50/2.8 OS HSM: 594$
Tamron 17-50/2.8 VC: 649$
I've used both those lenses (Sigma: bought and sold in 2010, Tamron: bought and sold in 2011) and they are NOWHERE near the EF-S 17-55 f/2.8 IS, be it IQ, built quality or the AF performance. Also those 2 lenses have had numerous quality control issues including but not limited to front focus, back focus, noisy stabilization & noisy AF issues. Spending $600 - $700 on those lenses is not worth it, when one can get a gem of a lens by spending another $300 more to get the EF 17-55 f/2.8 L IS
With Canon nowadays almost no lens below 1 grand is worth attention or stands clearly above the offer of other manufacturers.
First you were questioning Canon lenses "below $1500", when I gave you proof you quickly turn around and drop your figure to below $1000 ... no problem lets go through those lenses ... but let me agree with you on Nikkor 18-300 VR, I recently purchased this lens and it is a decent performer (not as good as 18-200 VR but decent nevertheless), yes Canon does not have an equivalent of 18-300 VR in price or size.
Here are some great lenses from Canon under $1000, both zooms and primes:
1. Canon EF-S 15-85mm lens = $649
2. Canon EF-S 10-20mm lens = $719
3. Canon EF 17-40mm f/4 L = $699
4. Canon EF 70-200 f/4 L = $674
5. Canon EF 100 f/2.8 L IS = $899
6. Canon EF 100 f/2.8 = $449
7. Canon EF 24mm IS = $649
8. Canon EF 28mm f/2.8 IS = $579
9. Canon EF 24mm f/1.8 = $449
10. Canon EF 50mm f/1.4 = $339
11. Canon EF 50mm Macro = $269
12. Canon EF 50mm f/1.8 = $94
13. Canon EF-S 60mm f/2.8 Macro = $399
14. Canon 85mm f/1.8 = $359
15. Canon EF 40mm f/2.8 = 149
16. Canon EF 70-300 = $499
17. Canon EF 135mm f/2 L = $949
Now here are a couple of bonus lenses for you: Canon EF 24-105 f/4 L IS & Canon EF-S 17-55 f/2.8 IS normally sell for under $1049 but there are dozens of online stores and regular stores who are selling it for $949 (i.e. below "1 grand"). By the way I have not listed several other decent lenses that are under "1 grand" and also those that can be purchased during sale or refurbished for under "1 grand" e.g. Canon EF 400 f/5.6 L or the 70-200 f/4 L IS.
If someone tells me that they cannot make great images with any one of those above lenses, then they first need to check all the millions of FANTASTIC images made with those lenses on flickr and many other sites, then they need to sign up for a course on some basic understanding of photography.
+1 and excellent points ... But IMHO you are wasting your time and barking up the wrong tree. This debate almost always ends up with hand waving and chest beating in a viscous circle usually something like this-
Comment: I have 4 canon bodies and they have poor IQ?
Q. Huh? Why do you say that?
A. Nikon has 14 stops of DR.
Q. So do you need those stops?
A. Well yes. I need to recover shadow detail from my shots I underexposed by 3 stops.
Q. If you shot correctly how would canon limit you?
A. But Nikon has more DR than Canon.
Q. But has Canon limited your shots in any way?
A. Always
Q. Can you post some pics where this has happened?
A. But Nikon has more DR than Canon
Q. But do you have any pics where you've been limited by Canon? If yes, post some shots.
A. Look at DXO, FM
Q. Don't you get it? Can you post any pictures where you have been limited by Canon?
A. But Nikon has more DR than Canon. Oh look at DXO, FM, the Internet is full of stuff ... Please google it yourself.
Q. You still don't get it. Can you post any pictures where YOUR shots have been limited by Canon?
A. But Nikon has more DR than Canon. Oh look at DXO, FM
Q. I give up
A. But Nikon has more DR than Canon. Oh look at DXO, FM. And you have the gall to accuse me of trolling
Q. You haven't posted any shots where you have been limited in your creativity by Canon ... How do you say Canon's IQ is bad?
A. But Nikon has more DR than Canon. Oh look at DXO, FM
Q. But how do you claim Canon's IQ is bad?
A. It is, Nikon has more DR than Canon.
Q. Then why don't you go ahead and shoot Nikon?
A. Silence
Q. Ohk, maybe that's the end of that.
A. How can you call me a troll? You have nothing in your response ... Canon is bad, Nikon has more DR than Canon, look at DXO, FM and other internet sites, and oh yes, I think Canon is expensive!
Q. I give up
