I wouldn't be able to afford it even for $4000. But logically, $6000+taxes - way too much. Obviously, Canon is aiming at agencies only. Photographers who pay for their own equipment won't be very happy to spend that much.
Well, don't kid yourself.
There are a LOT of people out there with enough disposable cash to buy this...$6K isn't a lot of money to a lot of people.
I'm not one of them....$6K is a lot for me, but it wouldn't break my household to drop $6K on a camera, I've spend that much before....but I tend to be one of those that doesn't spend much money on trivial crap, I save and save and once or twice a year I drop serious coin on things I want with no guilt at all.
I keep a zero balance on credit cards too, I only spend what I have saved (with the exception of deals giving me 1-2 years interest free, in which case I put the cash I have on hand for the purchase in savings and draw interest on it while paying the expense off.
