Animal Kingdom hasn't been under 145 per point direct from Disney for several years. There are a ton of AKL resale listings. I am asserting that SOME of those people who are listing their AKL for $80 or less bought in at prices above $140.
That's certainly true. But the market is driven more by sellers who CAN afford to take less. A seller isn't going to get $120 if there are many others asking $75. As long as there are significant numbers willing to sell for +/- $75, most sellers are forced into that price range.
The fact that it's been a while since AKV was offered in the $90s is meaningless. Not all sellers are short-term owners. Direct pricing was in the low $90s for years. Thousands of owners bought millions of points at that rate. And after 5-6 years of ownership, those individuals can easily sell for $75 per point and still come out ahead.
Look at resale pricing on each of the resorts and it's pretty easy to see similar trends. SSR, BLT, VGC, AKV, BCV, BWV...all of those resorts display resale pricing trends within a small margin of lowest direct pricing, with some adjustments based upon supply and popularity.
With the possible exception of Vero and Hilton Head, no DVC resort has had a prevailing resale price which was half its lowest direct price.
Not now...not during a recession. And given the popularity and anticipated small size of the Poly DVC, I wouldn't expect it to be the first to buck that trend. If (when) the next recession hits, it will be the high supply / low demand / short contract properties which are hit hardest.
