Thats a pretty weak, blanket statement. Plenty of us can afford one, and just choose not to. I can afford one, have owned one, and sold it. I didn't sell it because it wasn't a good bass, because it was. I just didn't see it being anything better than other Fenders out there that was much lighter, sounded as good or better, played as good or better, and cost a heck of a lot less. I actually traded an amazingly clean, unmolested '76 P I bought for $250 several years ago for a very nice acoustic guitar worth a few grand which I play every day, and own several other guitars that cost upward of around $3k, so saying that someone like me is just hating because we can't afford one is hilarious. I don't miss that 70's Fender for a second. My 2008 American Standard that weighs 8.4lbs and has been PLEK'd plays like butter, doesn't hurt the back and sounds just as good as the '76 I got rid of. I could buy a much more expensive car, but for my uses I just don't see the need to shell out for say an Audi wagon when my Subaru Outback keeps me perfectly happy. Doesn't mean I can't afford something more expensive.
Lots of people are skewed by nostalgia, "the good old days" and blurred perception. If those are qualities that are super important to you in a bass, than don't let me stop you from spending your money on whatever you want, even if that's a 70's Fender.
Not my cup of tea at all, but I guess your statement also holds up for the guys who buy a custom build that costs much more than a 70's Fender? Guess they can't afford one either.
