This is a phenomenon I have talked about extensively in other fora (and in one of the previous incarnations of this one). It is extremely ironic, IMHO opinion, that in a time when so many "gurus" have blabbed about the "democratization of wine", decent wine is quickly going back to the status of a luxury item.
Promote everyday drinking of wine with meals at home? Not so challenging when you can find plenty of under-$10 bottles that offer an interesting and tasty experience. But push the initial price point for "good wine" to $15-20 and all of a sudden we're in a completely different game.
I have often remarked how shocking it was to browse the selection of wines from Spain (a country that is practically dead to me now, wine-wise, but that used to be a great source for value reds and whites not ten years ago) at a well-stocked local retailer here in NYC. Where the average price of a bottle of Spanish wine may have once been closer to $10, now, if I whip out a calculator, that average is around $25...
A strange state of affairs. There ar regions that still give lots of great QPR wines, but price points, even for those regions, have moved up.
If it helps, I did a painful write-up about tasting a couple of hundred wines in search of something good at the old QPR category of $10-and-below. It appears here:

and here (Pt. 3)
and here (Pt. 4)
Gnarly work, that...
