Here's a theory...
When we bought in about 10 years ago, the price was the price - and there was a minimum. You could either afford it or not. You didn't have to be rich, but you had to be pretty comfortable with your personal budget situation.
Fast forward several years to SSR. Now there were "incentives", dollars off, developer points, gift cards, reduced point buy ins. I'm in marketing and that's something you try never to do, as you setup an expectation for incentives, sale prices, etc and people tend not to buy until they see some kind of deal. Thus the posts "Is this as good as it gets, or should I wait for a better deal?". Sure enough, with AKL there were incentives, deals, etc. With the incentives plus developer points it makes it look like there is a free vacation in your future with the payment for that somewhere down the road.
One result is that (in my opinion) there are more people buying in who maybe shouldn't. I've been on these Boards about 10 years and there are WAY more posts from folks who are trying to s t r e t c h a budget to afford 100 points and to finance, and to figure out if they can afford a monthly payment with the dues on top. Way more posts from people who have a higher interest rate because their credit is shaky, or don't have a regular income. More buying in using a tax refund for down payment or who expect their income to go up in the future. More posts from people who say "we always stay at Values because that is all we can afford, is this cheaper?". It used to be that you looked at the cost and either said "okay, we can do that" or you said "Yikes, we can't afford that kind of money". Now people are tending to say "well, maybe if we stretch...". I'm not making a personal indictment of anyone's personal situation here - it is what it is and everyone needs to make their own decisions about what to spend money on.
That being said, it is often folks on the margin or some kind of financial edge that will get caught when the economy crashes. The expected increase in pay doesn't come through, or there is some unexpected expense and money is tight, or there is a job loss. The "free" vacation with the developers points has been taken and it's time to be paying dues, but you can't take another vacation because air fare is so high. Paying dues for no vacation seems like a waste. When that happens you gotta sell - and I think there are more
DVC owners on that financial edge than there used to be. Now that the economy is having issues, those folks are selling.
Just a theory.
